Basic Life Support: an accessible tool in layperson training. REVISTA DA ASSOCIACAO MEDICA BRASILEIRA (1992) 2019; 65:1300-1307. [PMID: 31721963 DOI: 10.1590/1806-9282.65.10.1300] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/10/2019] [Accepted: 03/31/2019] [Indexed: 11/21/2022]
Abstract
OBJECTIVES 1) To evaluate the efficiency of a new method of training laypeople on cardiopulmonary resuscitation (CPR). 2) To assess previous knowledge of the participants. METHODS Instructors were trained according to the 2015 American Heart Association Guidelines, with emphasis on CPR. Dummies made with PET bottles were used, and a questionnaire was applied to the participants before and after training. Statistical analysis was performed in the R commander program. Participants with incomplete documents were excluded from the study. RESULTS Out of 101 participants, 96 were included: 69 lay people, 17 health professionals, and ten health students. There was an improvement in the overall performance after training (mean pre: 62.7%, mean post: 75.8%, p <0.01), also present in the following main concepts: "mouth-to-mouth breathing is not necessary" (p <0.01), "risk of contamination" (p <0.01), "compression technique" (p <0.01). The concepts "recognition of severity" and "what is chest compression" did not improve, but had good pre-test means, 96.8% and 81.2%. There was no statistical difference in the knowledge between the groups (laypeople vs. health professionals and students, pre=0,06 e post=0,33). CONCLUSION The tools used in training were efficient. However, further studies are necessary to assess the long-term impact of this intervention.

Comparing bystander response to a sudden cardiac arrest using a virtual reality CPR training mobile app versus a standard CPR training mobile app. Resuscitation 2019; 139:167-173. [PMID: 31005588 DOI: 10.1016/j.resuscitation.2019.04.017] [Citation(s) in RCA: 34] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2019] [Revised: 03/27/2019] [Accepted: 04/10/2019] [Indexed: 10/27/2022]
Abstract
BACKGROUND Using a mobile virtual reality (VR) platform to heighten realism for cardiopulmonary resuscitation (CPR) training has the potential to improve bystander response. OBJECTIVES We examined whether using a VR mobile application (mApp) for CPR training would improve bystander response compared with a standard mApp CPR training. METHODS We randomized lay bystanders to either our intervention arm (VR mApp) or our control arm (mApp). During a post-intervention skills test, we collected bystander response data (call 911, perform CPR, ask for an automated external defibrillator (AED)), along with CPR quality (chest compression (CC) rate and depth). Wilcox rank sum was used to analyze CC rate and CC depth as they were not normally distributed; Pearson's Chi-square was used to analyze Chain of Survival variables. RESULTS Between 3/2018 and 9/2018, 105 subjects were enrolled: 52 VR mApp and 53 mApp. Mean age was 46 ± 16 years, 34% were female, 59% were Black, and 17% were currently CPR trained (≤2 years). Bystander response was significantly higher in the VR mApp arm: called 911 (82% vs 58%, p = 0.007) and asked for an AED (57% vs 28%, p = 0.003). However there was no difference in CPR performed (98% vs 98%, p = NS) and the application of the AED (90% vs 93%, p = NS). When comparing the VR mApp to the mApp, mean CC rate was 104 ± 42 cpm vs 112 ± 30 cpm (p = NS), and mean CC depth was 38 ± 15 mm vs 44 ± 13 mm (p = 0.05). CONCLUSION The use of the VR mApp significantly increased the likelihood of calling 911 and asking for an AED, however, CC depth was decreased.

The effect of an International competitive leaderboard on self-motivated simulation-based CPR practice among healthcare professionals: A randomized control trial. Resuscitation 2019; 138:273-281. [PMID: 30946919 DOI: 10.1016/j.resuscitation.2019.02.050] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2018] [Revised: 02/11/2019] [Accepted: 02/18/2019] [Indexed: 01/04/2023]
Abstract
BACKGROUND Little is known about how best to motivate healthcare professionals to engage in frequent cardiopulmonary resuscitation (CPR) refresher skills practice. A competitive leaderboard for simulated CPR can encourage self-directed practice on a small scale. The study aimed to determine if a large-scale, multi-center leaderboard improved simulated CPR practice frequency and CPR performance among healthcare professionals. METHODS This was a multi-national, randomized cross-over study among 17 sites using a competitive online leaderboard to improve simulated practice frequency and CPR performance. All sites placed a Laerdal® ResusciAnne or ResusciBaby QCPR manikin in 1 or more clinical units - emergency department, ICU, etc. - in easy reach for 8 months. These simulators provide visual feedback during 2-minute compressions-only CPR and a performance score. Sites were randomly assigned to the intervention for the first 4-months or the second 4-months. Following any CPR practice by a healthcare professional, participants uploaded scores and an optional 'selfie' photo to the leaderboard. During the intervention phase, the leaderboard displayed ranked scores and high scores earned digital badges. The leaderboard did not display control phase participants. Outcomes included CPR practice frequency and mean compression score, using non-parametric statistics for analyses. RESULTS Nine-hundred nineteen participants completed 1850 simulated CPR episodes. Exposure to the leaderboard yielded 1.94 episodes per person compared to 2.14 during the control phase (p = 0.99). Mean CPR performance participants did not differ between phases: 90.7 vs. 89.3 (p = 0.19). CONCLUSION A competitive leaderboard was not associated with an increase in self-directed simulated CPR practice or improved performance.

Effectiveness of a One-minute Self-retraining for Chest Compression-only Cardiopulmonary Resuscitation: Randomized Controlled Trial. AEM EDUCATION AND TRAINING 2017; 1:200-207. [PMID: 30051035 PMCID: PMC6001494 DOI: 10.1002/aet2.10034] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/10/2016] [Revised: 02/27/2017] [Accepted: 03/09/2017] [Indexed: 06/08/2023]
Abstract
OBJECTIVES Although cardiopulmonary resuscitation (CPR) skills decay after training, little is known about appropriate retraining methods. Our aim was to evaluate the effectiveness of a 1-minute self-retraining (with automated assessment and feedback) at 3 months after the initial 45-minute chest compression-only CPR training in a simulated randomized controlled trial. METHODS After the initial 45-minute chest compression-only CPR training, participants were randomly assigned to either a 1-minute self-retraining group or a control group. Three months after the initial training, the self-retraining group individually attended the 1-minute self-retraining with a self-training device. The participants' resuscitation skills were evaluated by a 2-minute case-based scenario test 6 months after the initial training. The primary outcome was the number of correct chest compressions with appropriate depth. RESULTS A total of 109 subjects participated in this study. With regard to the primary outcome, the number of chest compressions performed at the appropriate depth, there was not a statistically significant difference between groups (136.5 [39.8-204.5] in the self-retraining group versus 88.0 [8.5-162.0] in the control group, p = 0.66). The number of total chest compressions in the self-retraining group was 214.0 (186.5-236.0), which was significantly greater (p = 0.01) than that of the control group (177.0 [117.5-215.0]). The time without chest compressions was significantly shorter in the self-retraining group (0 [0-5.3] seconds vs. 23.0 [0.5-47.0] seconds, p = 0.01). CONCLUSIONS The 1-minute self-retraining program with hands-on practice appears to help preserve certain chest compression skills. Further efforts to provide methods to maintain CPR skills should be considered.

Abstract
BackgroundEffective paediatric basic life support improves survival and outcomes. Current cardiopulmonary resuscitation (CPR) training involves 4-yearly courses plus annual updates. Skills degrade by 3–6 months. No method has been described to motivate frequent and persistent CPR practice. To achieve this, we explored the use of competition and a leaderboard, as a gamification technique, on a CPR training feedback device, to increase CPR usage and performance.ObjectiveTo assess whether self-motivated CPR training with integrated CPR feedback improves quality of infant CPR over time, in comparison to no refresher CPR training.DesignRandomised controlled trial (RCT) to assess the effect of self-motivated manikin-based learning on infant CPR skills over time.SettingA UK tertiary children's hospital.Participants171 healthcare professionals randomly assigned to self-motivated CPR training (n=90) or no refresher CPR training (n=81) and followed for 26 weeks.InterventionThe intervention comprised 24 h a day access to a CPR training feedback device and anonymous leaderboard. The CPR training feedback device calculated a compression score based on rate, depth, hand position and release and a ventilation score derived from rate and volume.Main outcome measureThe outcome measure was Infant CPR technical skill performance score as defined by the mean of the cardiac compressions and ventilations scores, provided by the CPR training feedback device software. The primary analysis considered change in score from baseline to 6 months.ResultsOverall, the control group showed little change in their scores (median 0, IQR −7.00–5.00) from baseline to 6 months, while the intervention group had a slight median increase of 0.50, IQR 0.00–33.50. The two groups were highly significantly different in their changes (p<0.001).ConclusionsA significant effect on CPR performance was demonstrated by access to self-motivated refresher CPR training, a competitive leaderboard and a CPR training feedback device.

Abstract
AbstractCardiopulmonary resuscitation is taught widely to both lay persons and health care oworkers. It is a challenging psychomotor skill. Concerns about its safety to the rescuer have centered around the risk of infectious disease exposure. A young nursing assistant developed a minimally symptomatic pneumothorax during CPR training. This case is the first reported example of this complication for a CPR trainee or provider. The literature is reviewed for complications for CPR provider and recipient and the relevant issues regarding the current status and future direction of this intervention.

Abstract
BACKGROUND The ability to respond quickly and effectively to a cardiac arrest situation rests on nurses being competent, prepared and up-to-date in the emergency life-saving procedure of cardiopulmonary resuscitation (CPR). This study aimed to determine the extent to which nurses acquire and retain CPR cognitive knowledge and psychomotor skills following CPR training courses. METHODS A quasi-experiment was used. CPR knowledge of 112 nurses was assessed via a questionnaire using valid multiple-choice questions. An observatory standard checklist was used and CPR performance on manikins was evaluated to assess psychomotor skills (before the course baseline, after the course, after 10 weeks and then 2 years after the 4 hours CPR training course). Scores were based on a scale of 1 to 20. RESULTS A mean baseline score of 10.67 (SD=3.06), a mean score of 17.81 (SD=1.41) after the course, 15.26 (SD=3.17) 10 weeks after and 12.86 (SD=2.25), 2 years after the 4 hours CPR training course was noticed. Acquisition of knowledge and psychomotor skills of the nurses following a four-hour training program was significant. However, significant deterioration in both CPR knowledge and psychomotor skills was observed 2 years after the training program among 42 nurses. CONCLUSION The study findings present strong evidence to support the critical role of repetitive periodic CPR training courses to ensure that nurses were competent, up to date and confident responders in the event of a cardiac arrest.

Abstract
The "chain of survival" (early access, early cardiopulmonary resuscitation, early defibrillation, and early advanced care) defines the proven interventions necessary for successful resuscitation and survival of patients with cardiac arrest. Low survival rates from cardiac arrest are not due to lack of understanding of effective interventions, but instead are due to weak links in the chain of survival and the inability of communities to make sure these links function in an efficient, timely, and coordinated fashion. This article reviews how quality is defined for each link, how communities can strengthen each link, and how communities can forge a strong relationship between each link. By optimizing local leadership and stakeholder collaboration, communities have the potential to vastly improve outcomes from this devastating disease.

Abstract
Background Guidelines recommend that all health care professionals should be able to perform cardiopulmonary resuscitation (CPR), including the use of an automated external defibrillator. Theoretical knowledge of CPR is then necessary. The aim of this study was to investigate how much theoretical knowledge in CPR would increase among all categories of health care professionals lacking training in CPR, in an intervention hospital, after a systematic standardised training. Their results were compared with the staff at a control hospital with an ongoing annual CPR training programme. Methods Health care professionals at two hospitals, with a total of 3144 employees, answered a multiple-choice questionnaire before and after training in CPR. Bootstrapped chi-square tests and Fisher's exact test were used for the statistical analyses. Results In the intervention hospital, physicians had the highest knowledge pre-test, but other health care professionals including nurses and assistant nurses reached a relatively high level post-test. Improvement was inversely related to the level of previous knowledge and was thus most marked among other health care professionals and least marked among physicians. The staff at the control hospital had a significantly higher level of knowledge pre-test than the intervention hospital, whereas the opposite was found post-test. Conclusions Overall theoretical knowledge increased after systematic standardised training in CPR. The increase was more pronounced for those without previous training and for those staff categories with the least medical education.

Abstract
BACKGROUND There is mismatch in age between those usually trained in CPR and those witnessing out-of-hospital cardiac arrest with mean age reported at 30 and 65 years old, respectively. Two tier mass CPR self-training with manikin-DVD sets using school children has been reported. We have studied high school students as first tier and encouraged them to train older people. METHODS Four separate groups were tested: students before or after training and second tier adults before or after training with first tier students as facilitators. CPR performance was videotaped and electronically documented on a Skillmeter Anne manikin. RESULTS Each student reported to train mean 2.8 extra persons, and 43% were aged 50 or older. Pre-training results were poor, while first and second tier persons performed equally well after training, and within ERC guideline recommendations. CONCLUSIONS People trained at home with a manikin-DVD set and high school students as facilitators were able to perform CPR as recommended by ERC guidelines with a reasonable percentage aged 50 or older.

Abstract
There is a public expectation that registered nurses are competent in their skills. Nurses need to know cardiopulmonary resuscitation (CPR) to enable them to safely and effectively provide appropriate CPR measures. The objectives of this descriptive study were (i) to investigate nurses' knowledge regarding CPR; and (ii) to identify barriers to appropriate CPR evaluation. One hundred questionnaires were distributed to nurses working in a public government hospital in Bahrain; 82 of these were returned. The results indicated that cognitive knowledge was not adequately retained. Fifty-eight per cent of respondents perceived recalling CPR information as easy or extremely easy. Only 7% of respondents passed the knowledge test. In general, those who had less education and experience did not recall essential CPR knowledge. This study identified a significant problem with the knowledge surrounding CPR. More concerning was the lack of professional responsibility in dealing with this inadequacy.

Abstract
This prospective study compared pre- and post-class performance in basic life support (BLS) on a recording manikin in a convenience sample of 34 health care workers undertaking a two-hour class provided by a hospital resuscitation department teaching the 2005 Resuscitation Council (UK) guidelines. On completion of training there were significant improvements in the proportion of subjects correctly performing a safe approach (14/34 vs. 25/33, 95%CI +11 to +55%, p=0.004), checking for response (17/34 vs. 24/32, 95%CI +1 to +46%, p=0.029), shouting for help (18/34 vs. 28/32, 95%CI +13 to +54%, p=0.002), opening the airway (6/34 vs. 26/32, 95%CI +42 to +79%, p<0.001), checking for breathing (9/34 vs. 27/32, 95%CI +35 to +74%, p<0.001), calling a cardiac arrest team (1/34 vs. 24/32, 95%CI +53 to +85%, p<0.001), and providing the correct compression to breath ratio (11/34 vs. 20/34, +3 to +48%, p=0.033). The median number of correct chest compressions increased from 3 to 41 (p<0.001) with improvements in adequate depth (median depth 36 vs. 40mm, p=0.006), although the compression rate was too fast before training and increased afterwards (median 123 vs. 147, p<0.001). Ventilation performance could not be measured accurately as the manikin was calibrated incorrectly by the manufacturers.

Abstract
RESEARCH ABSTRACT Adequate training in cardiopulmonary resuscitation (CPR) and use of an automated external defibrillator (AED) is an important component of a workplace safety training program. Barriers to traditional in-classroom CPR-AED training programs include time away from work to complete training, logistics, learner discomfort over being in a classroom setting, and instructors who include information irrelevant to CPR. This study evaluated differences in CPR skills performance between employees who learned CPR using a self-directed learning (SDL) kit and employees who attended a traditional instructor-led course. The results suggest that the SDL kit yields learning outcomes comparable to those obtained with traditional instructor-led courses and is a more time-efficient tool for CPR-AED training. Furthermore, the SDL kit overcomes many of the barriers that keep individuals from learning CPR and appears to contribute to bystanders' confidently attempting resuscitation.

Abstract
BACKGROUND Bystander cardiopulmonary resuscitation (CPR) decreases mortality from out-of-hospital cardiac arrest significantly. Accordingly, layperson CPR is an integral component in the chain of survival for out-of-hospital cardiac arrest victims. The near statewide incidence and location of layperson CPR is unknown. OBJECTIVE To determine true incidence and location of layperson CPR in the State of Arizona. METHODS The Save Hearts in Arizona Registry and Education (SHARE) program reviewed EMS first care reports submitted voluntarily by 30 municipal fire departments responsible for approximately 67% of Arizona's population. In addition to standard Utstein style data, information regarding the performance of bystander CPR, the vocation and medical training of the bystander and the location of the arrest were documented. RESULTS The total number of out-of-hospital adult arrests of presumed cardiac etiology reported statewide was 1097. Cardiac arrests occurred in private residences in 67%, extended care or medical facilities in 18%, and public locations in 15%. Bystander CPR was performed in 37% of all arrests, 24% of residential arrests, 76% of extended care or medical facility arrests, and 52% of public arrests. Bystander CPR provided an odds ratio of 2.2 for survival [95% CI 1.2-4.1]. Excluding cardiac arrests which occurred in the presence of bystanders with formal CPR training as part of their job description, layperson CPR was performed in 218 of 857 (25%) of cases. CONCLUSIONS The near statewide incidence of layperson CPR is extremely low. This low rate of bystander CPR is likely to contribute to the low overall survival rates from cardiac arrest. Public health officials should re-evaluate current models of public education on CPR.

Abstract
BACKGROUND Bystander CPR improves outcomes after out of hospital cardiac arrest. The length of current 4-h classes in cardiopulmonary resuscitation (CPR) is a barrier to more widespread dissemination of CPR training and older adults in particular are underrepresented in traditional classes. Training with a brief video self-instruction (VSI) program has shown that this type of training can produce short-term skill performance at least as good as that seen with traditional American Heart Association (AHA) Heartsaver training, although it is unclear whether there is comparable skill retention. METHODS AND RESULTS Two hundred and eight-five adults between the ages of 40 and 70 who had no CPR training within the past 5 years were assigned at random to a no-training control group, Heartsaver (HS) training, or one of three versions of brief VSI (i.e., self-trained-ST subjects). Post-training performance of CPR skills was assessed in a scenario format by human examiners and by sensored manikin at Time 1 (immediately post-training) and again at Time 2 (2 months post-training). Performance by controls was assessed only once. Significant (P<.001) decline was observed in the three measures recorded by examiners; assess responsiveness (from 72% to 60% for HS subjects and from 90% to 77% for ST subjects), call 911 (from 82% to 74% for HS subjects and from 71% to 53% for ST subjects), and overall performance (from 42% to 30% for HS subjects and from 60% to 44% for ST subjects). Significant (P<.001) decline was observed in two of three skills measured by a sensored manikin: ventilation volume (from 40% to 36% for HS subjects and from 61% to 41% for ST subjects, with a significant [P=.028] interaction) and correct hand placement (from 68% to 59% for HS subjects and from 80% to 64% for ST subjects). Heartsaver and self-trained subjects generally showed similar rates of decline. At Time 2, examiners rated trained subjects better than untrained controls in all skills except calling 911, where self-trained subjects did not differ from controls; manikin data revealed that trained subjects' performance was better than that of controls for ventilation volume, but had declined to the level of controls for both hand placement and compression depth. CONCLUSIONS Adults between 40 and 70 years of age who participated in a CPR VSI program experienced performance decline in their CPR skills after a post-training interval of 2 months. However, this decline was no greater than that seen in subjects who took Heartsaver training. The VSI program produced retention performance at least as good as that seen with traditional training. Additional effort is needed to improve both initial performance and retention of CPR skills. CONDENSED ABSTRACT Retention of CPR skills was compared 2 months post-training for adults between 40 and 70 years old who had taken either a traditional Heartsaver CPR course or a 22-min video self-directed training course. Although performance declines occurred in the 2-month interval, self-trained subjects generally demonstrated CPR skill retention equivalent to that of Heartsaver-trained subjects, although for both groups skill decline on some measures reached the level of untrained controls.

Prospective, randomized trial of the effectiveness and retention of 30-min layperson training for cardiopulmonary resuscitation and automated external defibrillators: The American Airlines Study. Resuscitation 2007; 74:276-85. [PMID: 17452070 DOI: 10.1016/j.resuscitation.2006.12.017] [Citation(s) in RCA: 102] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2006] [Revised: 12/11/2006] [Accepted: 12/11/2006] [Indexed: 11/24/2022]
Abstract
OBJECTIVE A head-to-head trial was conducted to compare laypersons' long-term retention of life-saving psychomotor and cognitive skills learned in the traditional multi-hour training format for basic cardiopulmonary resuscitation and automated external defibrillator use to those learned in an abbreviated (30 min) course. METHODS Laypersons were randomized to either: (1) the traditional multi-hour Heartsaver-Automated External Defibrillator (Heartsaver-AED) group; or (2) the 30-min course group (cardiopulmonary resuscitation, choking, and automated external defibrillator use). Immediately after training, and at 6 months, participants were provided identical individual testing scenarios. In addition to audio-video recordings, computerized recordings of compression rate/depth, ventilation rates, and related pauses were obtained and subsequently rated by blinded reviewers. RESULTS Performance following 30-min training was either equivalent or superior (p<0.007) to the multi-hour Heartsaver-Automated External Defibrillator training in all measurements, both immediately and 6 months after training. Although retention of certain skills deteriorated over the 6 months among a significant number of participants from both groups, 84% of the 30-min training group still was judged, overall, to perform cardiopulmonary resuscitation adequately. Moreover, 93% still were performing chest compressions adequately and 93% continued to apply the automated external defibrillator and deliver shocks correctly. CONCLUSIONS Using innovative learning techniques, 30-min cardiopulmonary resuscitation and automated external defibrillator training is as effective as traditional multi-hour courses, even after 6 months. Thirty-minute courses should decrease labor intensity, demands on resources, and time commitments for cardiopulmonary resuscitation courses, thus facilitating more widespread and frequent retraining.

Abstract
PURPOSE OF REVIEW Basic cardiopulmonary resuscitation, including use of automated external defibrillators, unequivocally saves lives. However, even when motivated, those wishing to acquire training traditionally have faced a myriad of barriers including the typical time commitment (3-4 h) and the number of certified instructors and equipment caches required. RECENT FINDINGS The recent introduction of innovative video-based self-instruction, utilizing individualized inflatable manikins, provides an important breakthrough in cardiopulmonary-resuscitation training. Definitive studies now show that many dozens of persons can be trained simultaneously to perform basic cardiopulmonary resuscitation, including appropriate use of an automated external defibrillator, in less than 30 min. Such training not only requires much less labor intensity and avoids the need for multiple certified instructors, but also, because it is largely focused on longer and more repetitious performance of skills, these life-saving lessons can be retained for long periods of time. SUMMARY Simpler to set-up and implement, the half-hour video-based self-instruction makes it easier for employers, churches, civic groups, school systems and at-risk persons at home to implement such training and it will likely facilitate more frequent re-training. It is now hoped that the ultimate benefit will be more lives saved in communities worldwide.

Abstract
OBJECTIVES Continuous chest-compression cardiopulmonary resuscitation (CCC-CPR) has been advocated as an alternative to standard CPR (STD-CPR). Studies have shown that CCC-CPR delivers substantially more chest compressions per minute and is easier to remember and perform than STD-CPR. One concern regarding CCC-CPR is that the rescuer may fatigue and be unable to maintain adequate compression rate or depth throughout an average emergency medical services response time. The specific aim of this study was to compare the effects of fatigue on the performance of CCC-CPR and STD-CPR on a manikin model. METHODS This was a prospective, randomized crossover study involving 53 medical students performing CCC-CPR and STD-CPR on a manikin model. Students were randomized to their initial CPR group and then performed the other type of CPR after a period of at least two days. Students were evaluated on their performance of 9 minutes of CPR for each method. The primary endpoint was the number of adequate chest compressions (at least 38 mm of compression depth) delivered per minute during each of the 9 minutes. The secondary endpoints were total compressions, compression rate, and the number of breaks taken for rest. The students' performance was evaluated on the basis of Skillreporter Resusci Anne (Laerdal, Wappingers Falls, NY) recordings. Primary and secondary endpoints were analyzed by using the generalized linear mixed model for counting data. RESULTS In the first 2 minutes, participants delivered significantly more adequate compressions per minute with CCC-CPR than STD-CPR, (47 vs. 32, p = 0.004 in the 1st minute and 39 vs. 29, p = 0.04 in the 2nd minute). For minutes 3 through 9, the differences in number of adequate compressions between groups were not significant. Evaluating the 9 minutes of CPR as a whole, there were significantly more adequate compressions in CCC-CPR vs. STD-CPR (p = 0.0003). Although the number of adequate compressions per minute declined over time in both groups, the rate of decline was significantly greater in CCC-CPR compared with STD-CPR (p = 0.0003). The mean number of total compressions delivered in the first minute was significantly greater with CCC-CPR than STD-CPR (105 per minute vs. 58 per minute, p < 0.001) and did not change over 9 minutes in either group. There were no differences in compression rates or number of breaks between groups. CONCLUSIONS CCC-CPR resulted in more adequate compressions per minute than STD-CPR for the first 2 minutes of CPR. However, the difference diminished after 3 minutes, presumably as a result of greater rescuer fatigue with CCC-CPR. Overall, CCC-CPR resulted in more total compressions per minute than STD-CPR during the entire 9 minutes of resuscitation.

A reference basic life support provider course for Europe. Resuscitation 2006; 69:413-9. [PMID: 16597481 DOI: 10.1016/j.resuscitation.2005.10.018] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2005] [Revised: 10/19/2005] [Accepted: 10/21/2005] [Indexed: 11/17/2022]
Abstract
BACKGROUND Good scientific evidence is scarce in relation to the effectiveness of different methods of teaching basic life support (BLS) to the general public. In order to test new courses or methods a reference course is needed as a comparative standard. OBJECTIVE To propose a reference BLS provider course that can be used as a comparator when testing new courses or teaching methods. METHODS All national resuscitation councils that are represented in the European Resuscitation Council (ERC) were sent a questionnaire about the BLS provider courses run by them or under their auspices. RESULTS Sixteen national resuscitation councils responded to the enquiry. Their responses regarding organisation, structure, content and methods of the courses were found to be remarkably consistent between European countries. Few issues had a high variance. CONCLUSIONS Based on the responses received, a reference BLS provider course for lay persons is suggested as a tool for research. The course duration is 3 h 15 min (excluding breaks), with 2 h 15 min practice time for the participants, 30 min for theory and 20 min for practical demonstrations by the instructor. A manual is distributed at the start of the course. The ratio of instructors to participants is one to six. The lectures are interactive between the instructor and the participants. Cardiopulmonary resuscitation (CPR) is practised on manikins in groups of six. A formal BLS scenario test may be held at the end of the course as part of a research study or if the candidates so request. It is suggested that by using this reference course during research into lay person BLS teaching, it will be easier to make comparisons between different studies.

Undergraduate nursing students' acquisition and retention of CPR knowledge and skills. NURSE EDUCATION TODAY 2006; 26:218-27.

Abstract
The ability to respond quickly and effectively to a cardiac arrest situation rests on nurses being competent in the emergency life-saving procedure of cardiopulmonary resuscitation (CPR). The aim of this study was to investigate the extent to which Irish nursing students acquire and retain CPR cognitive knowledge and psychomotor skills following CPR training. A quasi-experimental time series design was used. A pre-test, CPR training programme, post-test, and re-test were conducted. CPR knowledge was assessed by a multiple-choice assessment and psychomotor skills were assessed by observing CPR performance on a Resusci-Anne skill-meter manikin. The findings showed an acquisition in nurses' CPR knowledge and psychomotor performance following a 4h CPR training programme. Despite this, at no point in this study, did any nurse pass the CPR skills assessment. A deterioration in both CPR knowledge and skills was found 10 weeks following CPR training. However, students' knowledge and skills were improved over their pre-training scores, which clearly indicated a positive retention in CPR cognitive knowledge and psychomotor skills. The study findings present strong evidence to support the critical role of CPR training in ensuring that nursing students progress to competent and confident responders in the event of a cardiac related emergency.

Effectiveness of a 30-min CPR self-instruction program for lay responders: a controlled randomized study. Resuscitation 2005; 67:31-43.

Abstract
BACKGROUND The length of current 4-h classes in cardiopulmonary resuscitation (CPR) is a barrier to widespread dissemination of CPR training. The effectiveness of video-based self-instruction (VSI) has been demonstrated in several studies; however, the effectiveness of this method with older adults is not certain. Although older adults are most likely to witness out-of-hospital cardiac arrests, these potential rescuers are underrepresented in traditional classes. We evaluated a VSI program that comprised a 22-min video, an inflatable training manikin, and an audio prompting device with individuals 40-70 years old. The hypotheses were that VSI results in performance of basic CPR skills superior to that of untrained learners and similar to that of learners in Heartsaver classes. METHODS Two hundred and eighty-five adults between 40 and 70 years old who had had no CPR training within the past 5 years were assigned to an untrained control group, Heartsaver training, or one of three versions of VSI. Basic CPR skills were measured by instructor assessment and by a sensored manikin. RESULTS The percentage of subjects who assessed unresponsiveness, called the emergency telephone number 911, provided adequate ventilation, proper hand placement, and adequate compression depth was significantly better (P<0.05) for the VSI groups than for untrained controls. VSI subjects tended to have better overall performance and better ventilation performance than did Heartsaver subjects. CONCLUSIONS Older adults learned the fundamental skills of CPR with this training program in about half an hour. If properly distributed, this type of training could produce a significant increase in the number of lay responders who can perform CPR.

Uninterrupted chest compression CPR is easier to perform and remember than standard CPR. Resuscitation 2004; 63:123-30. [PMID: 15531062 DOI: 10.1016/j.resuscitation.2004.04.011] [Citation(s) in RCA: 53] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2004] [Revised: 04/21/2004] [Accepted: 04/21/2004] [Indexed: 10/26/2022]
Abstract
INTRODUCTION It has long been observed that CPR skills rapidly decline regardless of the modality used for teaching or criteria used for testing. Uninterrupted chest compression CPR (UCC-CPR) is a proposed alternative to standard single rescuer CPR (STD-CPR) for laypersons in witnessed unexpected cardiac arrest in adults. It delivers substantially more compressions per minute and may be easier to remember and perform than standard CPR. METHODS In this prospective study, 28 medical students were taught STD-CPR and UCC-CPR and then were tested on each method at baseline (0), 6, and 18 months after training. The students' performance for at least 90 s of CPR was evaluated based on video and Laerdal Skillreporter Resusci Anne recordings. RESULTS The mean number of correct chest compressions delivered per minute trended down over time in STD-CPR (23 +/- 3, 19 +/- 4 , and 15 +/- 3; P = 0.09) but stayed the same in UCC-CPR (43 +/- 9, 38 +/- 7, and 37 +/- 7 = 0.91) at 0, 6, and 18 months, respectively. The mean percentage of chest compressions delivered correctly fell over time in STD-CPR (54 +/- 6%, 35 +/- 6%, and 32 +/- 6%; P = 0.02) but stayed the same in UCC-CPR (34 +/- 5%, 41 +/- 7%, and 38 +/- 8%) at 0, 6, and 18 months, respectively. The number of chest compressions delivered per minute was higher in UCC-CPR at 0, 6, and 18 months (113 versus 44, P < 0.0001; 94 versus 47, P < 0.0001; and 92 versus 44, P < 0.001). The greater number of chest compressions was due to a mean ventilaroty pause of 13-14 s during STD-CPR at all three time points. CONCLUSIONS Chest compression performance during STD-CPR declined in repeated testing over 18 months whereas there was minimal decline in chest compressions performance on repeated testing of UCC-CPR. In addition, substantially more chest compressions were delivered during UCC-CPR compared to STD-CPR at all time points primarily because of long pauses accompanying rescue breathing.

Trials of teaching methods in basic life support (4): comparison of simulated CPR performance at unannounced home testing after conventional or staged training. Resuscitation 2004; 61:41-7. [PMID: 15081180 DOI: 10.1016/j.resuscitation.2003.12.014] [Citation(s) in RCA: 29] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2003] [Revised: 12/09/2003] [Accepted: 12/18/2003] [Indexed: 11/28/2022]
Abstract
This study compares the retention of basic life support (BLS) skills after 6 and 12 months by lay persons trained either in a conventional manner, or using a staged approach. Three classes, each of 2h, were offered to volunteers over a period of 4 months. For the conventional group, the second and third classes consisted of review of skills. Those in the staged group were first taught chest compression alone; chest compression with ventilation in a ratio of 50:5 was introduced at the second class; full standard CPR was taught at the third class. A total of 495 volunteers entered the study, 262 being randomly allocated to conventional training, and 233 to staged training. More of those who received staged training attended a second (78 volunteers) and third class (41 volunteers), compared with those who received conventional training (36 and 17, respectively). The objective of this study, however, was to compare the strategies of the different training methods. A total of 291 volunteers (167 conventional and 124 staged training) were available for unannounced home testing of full conventional CPR 6 months after initial training, and 260 volunteers (135 conventional and 125 staged training) were tested at 12 months. At 6 months, those taught by the staged method were significantly better at time to first compression (P < 0.0001), compression rate (P = 0.024), and hand position (P = 0.0001). At 12 months, those taught by the staged method were significantly better at shouting for help (P = 0.005), time to first compression (P < 0.0001), and compression depth (P = 0.003). Those taught conventionally were significantly better at checking for a carotid pulse at both 6 and 12 months (P < 0.0001). These results suggest that training lay persons in basic life support skills using a staged approach leads to overall better skill retention at 6 and 12 months, and has other advantages including a greater willingness to re-attend follow-up classes.

Abstract
This prospective study evaluated the acquisition and retention of skills in cardio-pulmonary resuscitation (CPR) and the use of the automated external defibrillator (AED) by lay volunteers involved in the Department of Health, England National Defibrillator Programme. One hundred and twelve trainees were tested immediately before and after and initial 4-h class; 76 were similarly reassessed at refresher training 6 months later. A standardised test scenario that required assessment of the casualty, CPR and the use of on AED was evaluated using recording manikin data and video recordings. Before training only 44% of subjects delivered a shock. Afterwards, all did so and the average delay to first shock was reduced by 57 s. All trainees placed the defibrillator electrodes in an "acceptable" position after training, but very few did so in the recommended "ideal" position. After refresher training 80% of subjects used the correct sequence for CPR and shock delivery, yet a third failed to perform adequate safety checks before all shocks. The trainees self-assessed AED competence score was 86 (scale 0-100) after the initial class and their confidence that they would act in a real emergency was rated at a similar level. Initial training improved performance of all CPR skills, although all except compression rate had deteriorated after 6 months. The proportion of subjects able to correctly perform most CPR skill was higher following refresher training that after the initial class. Although this course was judged to be effective in teaching delivery of counter-shocks, the need was identified for more emphasis on positioning of electrodes, pre-shock safety checks, airway opening, ventilation volume, checking for signs of a circulation, hand positioning, and depth and rate of chest compressions.

Abstract
This randomised controlled trial used a manikin model of cardiac arrest to compare skill performance in untrained lay persons randomised to receive either compression-only telephone CPR (Compression-only tel., n=29) or standard telephone CPR instructions (Standard tel., n=30). Performance was evaluated during standardised 10 min cardiac arrest simulations using a video recording and data from a laptop computer connected to the training manikin. A number of subjects in both groups did not open the airway. More than 75% in the Standard tel. group failed to deliver two effective initial rescue breaths, and only 17% provided an adequate inflation volume for subsequent breaths, delivering a median of only five inflations during the entire scenario. Most subjects in both groups gave chest compressions that were too shallow and at an inappropriately rapid rate. Hand position was also poor, but was worse in the group given simplified instructions. There was a significant delay to first compression in both groups, although this interval was shortened by over a minute when ventilations were eliminated from the telephone instruction algorithm (245 vs. 184 s, P<0.001). Over two-and-a-half times as many chest compressions were delivered during an average ambulance response time with compression-only telephone directions compared with standard CPR (461 vs. 186, P<0.001). These variables may be critical in predicting survival from out-of-hospital cardiac arrest. Further research is necessary to establish if modifications to scripted telephone instructions can remedy the identified performance deficiencies. Eliminating instructions for rescue breaths from scripted telephone directions will have little impact on the ventilation of most patients. Research is required to determine if the consequent reduction in the delay to starting chest compressions and the significant increase in the number of compressions delivered can increase survival from out-of-hospital cardiac arrest.

Abstract
The objectives of this study are to (1). quantify prior cardiopulmonary resuscitation (CPR) training in households of patients presenting to the Emergency Department (ED) with or without chest pain or ischaemic heart disease (IHD); (2). evaluate the willingness of household members to undertake CPR training; and (3). identify potential barriers to the learning and provision of bystander CPR. A cross-sectional study was conducted by surveying patients presenting to the ED of a metropolitan teaching hospital over a 6-month period. Two in five households of patients presenting with chest pain or IHD had prior training in CPR. This was no higher than for households of patients presenting without chest pain or IHD. Just under two in three households of patients presenting with chest pain or IHD were willing to participate in future CPR classes. Potential barriers to learning CPR included lack of information on CPR classes, perceived lack of intellectual and/or physical capability to learn CPR and concern about causing anxiety in the person at risk of cardiac arrest. Potential barriers to CPR provision included an unknown cardiac arrest victim and fear of infection. The ED provides an opportunity for increasing family and community capacity for bystander intervention through referral to appropriate training.

Abstract
United Christian Hospital initiated a doctor-based cardiopulmonary resuscitation (CPR) Program. It is a two-hour, focused, adult CPR course, suitable for adults of different age groups and of different educational levels. The course was rated highly by the participants. Most trainees acquired CPR knowledge and skills, and had confidence to perform CPR. This type of training could improve the rate of bystander CPR for out-of-hospital cardiac arrest patients in this region. Avoiding the complexity and pass-fail psychology that is used in the traditional CPR training curriculum, it can be an alternative to the traditional four-hour instructor-based Basic Life Support (BLS) course.

Abstract
A randomised controlled trial comparing staged teaching of cardiopulmonary resuscitation (CPR) with conventional training provided the additional opportunity to investigate skill acquisition and retention in those attending conventional CPR classes. All subjects were tested immediately after their first instruction period and again at 6-9 months at an unheralded home visit. We were able to assess how far performance was related to poor acquisition of skills and how far it was related to skill decay. Out of 262 subjects who were randomised to receive conventional CPR instruction, 166 were available for home testing at 6-9 months. An invitation to attend for re-training had been accepted by 39 of them. The remaining 127 who attended only a single class comprise the principal study group, with additional comparative observations on the smaller re-trained cohort. Important failings were observed in the acquisition of skills in all modalities tested after the initial instruction. These were particularly marked in skills related to ventilation. Immediately after a class, 68% of trainees performed an effective check of breathing, but only 33% opened the airway as taught and no more than 18% provided an ideal ventilation volume. The technique of chest compression was also less than ideal. Although 80% of subjects placed their hands in an acceptable position, compression to an adequate depth and an adequate rate of compression were achieved by 54 and 63%, respectively. Seventy-eight percent demonstrated a careful approach, and 46% remembered to call for help. A carotid pulse check was simulated by 61% of trainees. When tested 6-9 months later, skill deterioration from this baseline was observed in all modalities tested except for the ventilation volume. The skill decay was significant (P<0.05) for the careful approach, performing an effective breathing check, the carotid pulse check, placing the hands in an acceptable position for chest compression, and compressing at an optimal rate. The minority who attended for re-training showed a trend to protection against skill decay for seven of the ten variables, compared with those who had attended only one training session. This improvement was significant for only two of them, but all were relatively small with limited practical value. Many who attend conventional CPR classes fail to acquire the necessary skills, and the skills that are acquired decline appreciably over the subsequent 6-9 months. The value of conventional re-training was modest in this study of community volunteers.

Abstract
Teaching CPR in stages is a strategy designed to improve skill acquisition and retention. This method has been compared with conventional teaching in a randomised trial involving 495 volunteers. The first ('bronze') stage was simplified by omitting ventilation and giving compressions in sets of 50 with pauses to open the victim's airway; in the second ('silver') stage ventilation was introduced in a ratio of 50 compressions to five breaths, and in the third ('gold') stage, the volunteers were converted to conventional CPR. 51% of those taught by this method reattended for the second ('silver') stage compared with 25% who were taught conventional CPR and advised to return for a revision session. 38% of the staged group reattended for the third ('gold') compared with 8% for the conventional group. Modest improvement in skill acquisition has earlier been reported for the 'bronze' stage teaching, and this has been followed by better performance in some of the components tested after the subsequent stages. Comparisons after the 'gold' stage were limited by the small numbers who reattended for a third session of conventional training, but no special difficulties were noted in changing the ratio of compressions to ventilation that was necessary to convert the staged training volunteers to conventional CPR. The increased number of compressions that can be achieved by teaching 'bronze' stage CPR with no ventilation was retained, to a lesser degree, when the 'silver' ratio of 50 compressions to five breaths was compared with the conventional 15:2 ratio. Our observations suggest that during the first critical 8 min of a resuscitation attempt, 58% more compressions might be delivered by using the 50:5 ratio - an increase that is likely to result in a significant augmentation of blood flow with important clinical implications. More comparative information will become available when the results of unannounced home testing are analysed.

Abstract
Immediate activation of the emergency medical service (EMS) and cardiopulmonary resuscitation (CPR) increases the incidence of return of spontaneous circulation and the number discharged from hospital. The American Heart Association (AHA) and the European Resuscitation Council describe CPR as an ordinate sequence of eight steps. The objectives of this study were to assess the general knowledge of EMS and CPR and to analyse the retention of the CPR steps 2 months after a Basic Life Support (BLS)-course conducted according to AHA standards. We studied two populations from the same geographical area, law enforcement agents (LEA), since they are often the first to intervene, and high school students (HSS) since they are more likely to participate in such courses. HSS were more responsive and receptive than LEA. In order to increase the retention of the sequence of CPR steps, the number of steps should be reduced and refresher courses should be included in training programmes. Early access and early CPR are still not completely effective in the geographical area studied.

Abstract
BACKGROUND Information from the Swedish Cardiac Arrest Registry was used to investigate: (a) The proportion of patients suffering an out-of-hospital cardiac arrest who were given bystander cardiopulmonary resuscitation (B-CPR). (b) Where and by whom B-CPR was given. (c) The effect of B-CPR on survival. METHOD a prospective, observational study of cardiac arrests reported to the Swedish Cardiac Arrest Registry. Analyses were based on standardised reports of out-of-hospital cardiac arrests from ambulance organisations in Sweden, serving 60% of the Swedish population. From 1983 to 1995 approximately 15-20% of the population had been trained in CPR. RESULTS Of 9877 patients, collected between January 1990 and May 1995, B-CPR was attempted in 36%. In 56% of these cases, the bystanders were lay persons and in 25% they were medical personnel. Most of the arrests took place at home (69%) and only 23% of these patients were given B-CPR in contrast to cardiac arrest in other places where 53% were given CPR. Survival to 1 month was significantly higher in all cases that received B-CPR (8.2 vs. 2.5%). The odds ratio for survival to 1 month with B-CPR was in a logistic regression analysis 2.5 (95% CI 1.9-3.1). CONCLUSIONS In Sweden, the willingness and ability to perform B-CPR appears to be relatively widespread. More than half of B-CPR was performed by laypersons. B-CPR resulted in a two to threefold increase in survival.

Abstract
OBJECTIVE bystander cardiopulmonary resuscitation (CPR) is performed infrequently in Japan. We conducted this study to identify Japanese attitudes toward the performance of bystander CPR. METHODS participants were asked about their willingness to perform CPR with varying scenarios and CPR techniques (mouth-to-mouth ventilation plus chest compression (MMV plus CC) versus chest compression alone (CC)). RESULTS a total of 1302/1355 individuals completed the questionnaire, including high school students, teachers, emergency medical technicians, medical nurses, and medical students. About 2% of high school students, 3% of teachers, 26% of emergency medical technicians, 3% of medical nurses and 16% of medical students claimed they would 'definitely' perform MMV plus CC on a stranger. However, 21-72% claimed they would prefer the alternative of performing CC alone. Respondents claimed their unwillingness to perform MMV is not due to the fear of contracting a communicable disease, but the lack of confidence in their ability to perform CPR properly. CONCLUSION in all categories of respondents, willingness to perform MMV plus CC for a stranger was disappointingly low. Better training in MMV together with teaching awareness that CC alone can be given should be instituted to maximize the number of potential providers of CPR in the community, even in communities where the incidence of HIV is very low.

Abstract
BACKGROUND Bystander cardiopulmonary resuscitation (CPR) without assisted ventilation may be as effective as CPR with assisted ventilation for ventricular fibrillatory cardiac arrests. However, chest compressions alone or ventilation alone is not effective for complete asphyxial cardiac arrests (loss of aortic pulsations). The objective of this investigation was to determine whether these techniques can independently improve outcome at an earlier stage of the asphyxial process. METHODS AND RESULTS After induction of anesthesia, 40 piglets (11.5+/-0.3 kg) underwent endotracheal tube clamping (6.8+/-0.3 minutes) until simulated pulselessness, defined as aortic systolic pressure <50 mm Hg. For the 8-minute "bystander CPR" period, animals were randomly assigned to chest compressions and assisted ventilation (CC+V), chest compressions only (CC), assisted ventilation only (V), or no bystander CPR (control group). Return of spontaneous circulation occurred during the first 2 minutes of bystander CPR in 10 of 10 CC+V piglets, 6 of 10 V piglets, 4 of 10 CC piglets, and none of the controls (CC+V or V versus controls, P<0.01; CC+V versus CC and V combined, P=0.01). During the first minute of CPR, arterial and mixed venous blood gases were superior in the 3 experimental groups compared with the controls. Twenty-four-hour survival was similarly superior in the 3 experimental groups compared with the controls (8 of 10, 6 of 10, 5 of 10, and 0 of 10, P<0.05 each). CONCLUSIONS Bystander CPR with CC+V improves outcome in the early stages of apparent pulseless asphyxial cardiac arrest. In addition, this study establishes that bystander CPR with CC or V can independently improve outcome.

Abstract
OBJECTIVE Paramedics (EMT-Ps) often care for patients having an acute myocardial infarction (AMI). The benefit of early administration of aspirin in AMI is well established. This study was undertaken to determine whether EMT-Ps are able to retain information regarding the use of aspirin in AMI after a standard didactic session. METHODS The EMT-Ps from a suburban EMS system with an annual call volume of 4,000 were given a 12-question test regarding the out-of-hospital use of aspirin in AMI. They then received a 30-minute lecture about the use of aspirin in the out-of-hospital venue. Aspirin was then put into the treatment protocols for AMI. Three months after the educational session, a follow-up test was administered. A paired, two-tailed t-test was used to compare pretest and posttest scores with a p < or = 0.05 for statistical significance. RESULTS The study was completed by 22 of 25 EMT-Ps. The scores on the pretest ranged from 50% to 100% correct, with an average score of 83%. The posttest scores ranged from 83% to 100%, with an average score of 94% (p = 0.002). The questions missed on the posttest were regarding: 1) the length of the effects of aspirin, 2) the bronchospastic effects of aspirin, and 3) the recently instituted indications for its out-of-hospital use. All paramedics correctly identified the contraindications to aspirin use. CONCLUSION These results suggest that EMT-Ps can retain information regarding the out-of-hospital use of aspirin for AMI after a standard didactic session. Further study is needed to determine how this information is clinically applicable.

Abstract
STUDY OBJECTIVE Despite the proven efficacy of cardiopulmonary resuscitation (CPR), only a small fraction of the population knows how to perform it. As a result, rates of bystander CPR and rates of survival from cardiac arrest are low. Bystander CPR is particularly uncommon in the African American community. Successful development of a simplified approach to CPR training could boost rates of bystander CPR and save lives. We conducted the following randomized, controlled study to determine whether video self-instruction (VSI) in CPR results in comparable or better performance than traditional CPR training. METHODS This randomized, controlled trial was conducted among congregational volunteers in an African American church in Atlanta, GA. Subjects were randomly assigned to receive either 34 minutes of VSI or the 4-hour American Heart Association "Heartsaver" CPR course. Two months after training, blinded observers used explicit criteria to assess CPR performance in a simulated cardiac arrest setting. A recording manikin was used to measure ventilation and chest compression characteristics. Participants also completed a written test of CPR-related knowledge and attitudes. RESULTS VSI trainees displayed a comparable level of performance to that achieved by traditional trainees. Observers scored 40% of VSI trainees competent or better in performing CPR, compared with only 16% of traditional trainees (absolute difference 24%, 95% confidence interval 8% to 40%). Data from the recording manikin confirmed these observations. VSI trainees and traditional trainees achieved comparable scores on tests of CPR-related knowledge and attitudes. CONCLUSION Thirty-four minutes of VSI can produce CPR of comparable quality to that achieved by traditional training methods. VSI provides a simple, quick, consistent, and inexpensive alternative to traditional CPR instruction, and may be used to extend CPR training to historically underserved populations.

Abstract
OBJECTIVE To compare the efficacy of four methods of simulated single-rescuer bystander cardiopulmonary resuscitation (CPR) in a clinically relevant swine model of prehospital pediatric asphyxial cardiac arrest. DESIGN Prospective, randomized study. SUBJECTS Thirty-nine anesthetized domestic piglets. INTERVENTIONS Asphyxial cardiac arrest was produced by clamping the endotracheal tubes of the piglets. For 8 mins of simulated bystander CPR, animals were randomly assigned to the following groups: group 1, chest compressions and simulated mouth-to-mouth ventilation (FI(O2) = 0.17, FI(CO2) = 0.04) (CC+V); group 2, chest compressions only (CC); group 3, simulated mouth-to-mouth ventilation only (V); and group 4, no CPR (control group). Standard advanced life support was then provided, simulating paramedic arrival. Animals that were successfully resuscitated received 1 hr of intensive care support and were observed for 24 hrs. MEASUREMENTS AND MAIN RESULTS Electrocardiogram, aortic blood pressure, right atrial blood pressure, and end-tidal CO2 were monitored continuously until the intensive care period ended. Arterial and mixed venous blood gases were measured at baseline, 1 min after cardiac arrest, and 7 mins after cardiac arrest. Minute ventilation was determined during each minute of bystander CPR. Survival and neurologic outcome were determined. Twenty-four-hour survival was attained in eight of 10 group 1 (CC+V) piglets vs. three of 14 group 2 (CC) piglets (p < or = .01), one of seven group 3 (V) piglets (p < or = .05), and two of eight group 4 (control) piglets (p < or = .05). Twenty-four-hour neurologically normal survival occurred in seven of 10 group 1 (CC+V) piglets vs. one of 14 group 2 (CC) piglets (p < or = .01), one of seven group 3 (V) piglets (p < or = .05), and none of eight group 4 (control) piglets (p < or = .01). Arterial oxygenation and pH were markedly better during CPR in group 1 than in group 2. Within 5 mins of bystander CPR, six of 10 group 1 (CC+V) piglets attained sustained return of spontaneous circulation vs. only two of 14 group 2 (CC) piglets and none of the piglets in the other two groups (p < or = .05 for all groups). CONCLUSIONS In this pediatric asphyxial model of prehospital single-rescuer bystander CPR, chest compressions plus simulated mouth-to-mouth ventilation improved systemic oxygenation, coronary perfusion pressures, early return of spontaneous circulation, and 24-hr survival compared with the other three approaches.

Abstract
Existing cardiopulmonary resuscitation (CPR) training programmes have failed to reach those most likely to witness a cardiac arrest, such as families of cardiac patients. In 1993, the Scottish Health Service Advisory Committee suggested that CPR training could be offered as part of cardiac rehabilitation programmes. A survey was carried out to identify the current extent and nature of such training and factors influencing its provision. Questionnaires were mailed to all the 45 Scottish cardiac rehabilitation programmes on the British Heart Foundation's register. A 93% response rate was achieved. Only 37% of programmes provided information to families about attending a CPR course and 37% actually provided CPR training The numbers trained by these programmes were very small. Hospital programmes were significantly more likely than community programmes to provide CPR training (chi2 = 6.65, P < 0.01) as were those which included an exercise component (chi2 = 7.63, P < 0.01). Reasons for not providing training ranged from lack of resources and lack of staff training, to not having considered it. CPR training is provided as part of cardiac rehabilitation programmes to a limited extent. Ways of recruiting and increasing the number of family members of cardiac patients who are trained in CPR need to be found.

Abstract
Basic life support is a crucial part of the Chain of Survival. Unfortunately, however the skill is complex and cannot readily be acquired--let alone retained--in the course of a single training session. Although the problem has long been recognised, no new strategies have been widely implemented to counter the problem. We believe that staged teaching of CPR might provide a solution, and we have devised a program to test this new method. It involves three stages of instruction that we have called bronze, silver, and gold standards. The bronze standard involves opening the airway and providing chest compression without active ventilation: this alone may widen the window of opportunity for successful defibrillation in adult victims in out-of-hospital cardiac arrest. Ventilation is introduced at silver stage using a ratio of 50:5, with emphasis on its value in the resuscitation of children being used as motivation to bring people back for a second period of instruction. The gold stage teaches conventional CPR. A pilot study has been encouraging and a randomized trial on skill acquisition and skill retention is planned.
