Patient perspectives of airway clearance techniques in bronchiectasis. Physiother Theory Pract 2024; 40:505-515. [PMID: 36124537 DOI: 10.1080/09593985.2022.2126741] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2022] [Revised: 09/13/2022] [Accepted: 09/13/2022] [Indexed: 10/14/2022]
Abstract
INTRODUCTION While airway clearance techniques (ACTs) are recommended for individuals with bronchiectasis, data suggests the use of and adherence to ACTs is poor. OBJECTIVE This study aimed to identify patient perceptions regarding ACTs, the barriers and facilitators to ACTs, and factors affecting adherence. METHODS A multi-center qualitative study using in-depth semi-structured interviews of individuals with bronchiectasis was undertaken. All interviews were audio recorded and transcribed verbatim. Data was analyzed using the thematic framework approach described by Braun and Clark. NVIVO™ 12 software assisted with coding and thematic analysis of the interview transcripts. Data saturation was achieved when no new common themes were identified. Findings were summarized into major conceptual themes. Participant demographic data was also obtained. RESULTS Twenty-four participants participated in semi-structured interviews. The main facilitators to using ACTs included a perceived health and quality of life benefit, a tailored approach to ACTs and the use of self-management strategies. Main barriers included lack of time and motivation, lack of access to resources, and a lack of perceived health benefit. A number of factors were identified by participants that may help promote adherence including combining and trialing different ACTs, receiving regular ACT reviews and education from physiotherapists, and having good social support. CONCLUSION To assist the personalized prescription of ACTs, these facilitators and barriers should be considered by clinicians to help promote adherence and improve patient outcomes.

Efficacy of an oscillating positive expiratory pressure device in patients with Mycobacterium avium complex pulmonary disease. J Infect Chemother 2024:S1341-321X(24)00003-5. [PMID: 38182008 DOI: 10.1016/j.jiac.2024.01.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2023] [Revised: 12/26/2023] [Accepted: 01/02/2024] [Indexed: 01/07/2024]
Abstract
Patients with Mycobacterium avium complex pulmonary disease (MAC-PD) often suffer from chronic symptoms such as sputum production, which reduces quality of life. Oscillatory positive expiratory pressure (OPEP) devices are used in physiotherapy to promote the clearance of respiratory secretions. We report two cases of improved lung function and improved scores on the Leicester Cough Questionnaire (LCQ) and the Breathlessness, Cough and Sputum Scale (BCSS) after the use of OPEP in patients with MAC-PD where treatment with guideline-based therapy, including amikacin liposome inhalation suspension, had proved ineffective for symptoms. Use of OPEP might maximize the efficacy of therapy and thereby improves outcomes in patients with MAC-PD. It is important to use both guideline-based therapy and OPEP, especially in patients whose health-related quality of life is affected by sputum symptoms. Further prospective studies are warranted to assess the benefit of adding OPEP to guidelines concerning therapy for patients with MAC-PD and sputum symptoms.

Breathing better: A tech-monitored study of positive expiratory pressure and reading aloud for chronic obstructive pulmonary disease. Int J Nurs Pract 2023; 29:e13198. [PMID: 37653574 DOI: 10.1111/ijn.13198] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Revised: 07/23/2023] [Accepted: 08/20/2023] [Indexed: 09/02/2023]
Abstract
BACKGROUND Breathing exercises, such as diaphragmatic breathing and positive expiratory pressure (PEP), relieve breathlessness in people with chronic obstructive pulmonary disease (COPD). AIM This study aimed to investigate the effects of breathing exercises with PEP and reading aloud on vital signs, fatigue level, severity of dyspnoea and respiratory function parameters in patients with COPD. DESIGN The study followed a randomized controlled trial of COPD patients from a single hospital in eastern Turkey. METHODS The study included 103 patients who were randomly assigned to receive pre-reading exercises, breathing exercises with a PEP device or no intervention for 8 weeks. RESULTS The use of a PEP device improved oxygen saturation, forced expiratory volume in 1 s (FEV1 ) and FEV1 /forced vital capacity (FVC) values and reduced fatigue and dyspnoea severity. Reading aloud lowered the mean arterial pressure and reduced fatigue and dyspnoea severity. CONCLUSION The study concludes that PEP devices and reading aloud can improve respiratory function in patients with COPD. Additionally, reading aloud is an accessible, easy-to-implement and economically feasible method for treating COPD symptoms.

Effectiveness of the use of an oscillating positive expiratory pressure device in bronchiectasis with frequent exacerbations: a single-arm pilot study. Front Med (Lausanne) 2023; 10:1159227. [PMID: 37250647 PMCID: PMC10213442 DOI: 10.3389/fmed.2023.1159227] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2023] [Accepted: 04/19/2023] [Indexed: 05/31/2023] Open
Abstract
Impaired airway clearance in patients with non-cystic fibrosis bronchiectasis causes frequent bacterial infection, chronic inflammation, and progressive tissue destruction. We aimed to evaluate whether an oscillating positive expiratory pressure (OPEP) device could allow effective sputum expectoration and prevent acute exacerbations in patients with bronchiectasis who had frequent acute exacerbations. This open-label, single-arm, prospective study included 17 patients who experienced three or more acute exacerbations in the past year. We evaluated the prevention of acute exacerbations, subjective symptom improvement, and change in sputum amount during the use of the Aerobika (Trudell Medical International, London, ON) OPEP device twice daily for 6 months. Of all enrolled patients, only two acute exacerbations occurred during the study period, indicating a significant decrease compared with the number of acute exacerbations before the device use (p < 0.001). Additionally, Bronchiectasis Health Questionnaire score changed from 58.7 to 66.6, showing significant improvement over the treatment period (p < 0.001). The largest sputum volume was observed 3 months after OPEP device use (baseline: 10 ml, 3rd month 25 ml, p = 0.325). There were no major adverse events related to the use of OPEP devices. Twice-daily physiotherapy with OPEP device in patients with bronchiectasis who have frequent exacerbations may facilitate symptomatic improvement and prevention of acute exacerbations without serious adverse events.

The effectiveness of additional long-term use of bottle-positive expiratory pressure in chronic obstructive pulmonary disease: A single-blind, randomized study. Turk J Phys Med Rehabil 2022; 68:195-204. [PMID: 35989964 PMCID: PMC9366481 DOI: 10.5606/tftrd.2022.8239] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Accepted: 05/26/2021] [Indexed: 11/30/2022] Open
Abstract
Objectives
This study aimed to investigate the long-term use of bottle-positive expiratory pressure (PEP) in addition to breathing exercises as a home-based rehabilitation aid on exercise capacity, spirometric parameters, and quality of life in chronic obstructive pulmonary disease (COPD) patients.
Patients and methods
From a total of 30 patients with stable moderate-to-severe COPD, 24 (22 males, 2 females; mean age: 62.4+7.2 years; range, 40 to 75 years) were included in the final study and randomized into two groups: the group that performed breath retaining techniques and the group that was instructed to use the bottle-PEP in addition to these techniques. Patients were evaluated with modified Medical Research Council scale, COPD assessment test (CAT), spirometry, St. George`s Respiratory Questionnaire (SGRQ), and 6-min walk distance (6MWD) before, three months and six months after the initiation of the program.
Results
In the bottle-PEP group, patients` mean 6MWD increased from 380.6±67.6 to 444.1±22.0 m (p=0.002), the mean CAT score decreased from 17.8±36.8 to 12.9±6.2 (p=0.03), and the mean SGRQ total score significantly decreased from 57.1±23.1 to 47.6±21.9 (p<0.05) after three months. The improvement in 6MWD continued in six months but disappeared in SGRQ and CAT scores. In the exercise group, only the 6MWD improved, and there were no significant improvements in other parameters regardless of time. There were no significant differences between the groups in any of the parameters at any follow-up session.
Conclusion
While bottle-PEP does not significantly contribute when added to breathing exercises in patients with moderate-to-severe COPD in improving function and quality of life, it can be used as a safe choice in patients` home rehabilitation programs.

Abstract
Large airway collapse (LAC) describes the phenomenon of excessive, abnormal, inward movement of the large airways (i.e. trachea and/or main bronchi and/or bronchus intermedius) occurring during the expiratory phase of the respiratory cycle. It is an increasingly well-recognised problem and a prevalent comorbidity in other chronic respiratory conditions (e.g. COPD and asthma). LAC is associated with pervasive respiratory features such as a barking cough, exertional dyspnoea and an increased propensity to lower respiratory tract infection. These symptoms are unpleasant, and patients are often limited in their daily life and their function. The pathophysiology of this condition impairs airway clearance and can cause breathlessness and exercise intolerance, due to a loss of airway patency during expiratory flow. Dysfunctional adaptations to breathing and coughing may further amplify symptoms. This article provides, for the first time, clinically focused physiotherapeutic intervention advice based on our understanding of the pathophysiology of LAC, to support conservative management. It uses the available evidence from LAC, transferable evidence from other conditions and knowledge based on clinical experience. It proposes a practical "ABC model" to ensure physiotherapy assessment and treatments are centred around optimising three key clinical areas: Airways, including airway clearance and cough; Breathing, including breathlessness and breathing pattern; and Capacity for exercise, including an assessment of functional exercise ability.

Abstract
Rationale: Sputum retention in chronic obstructive pulmonary disease (COPD) is a troubling symptom and can lead to reduced quality of life and increased exacerbations. Airway clearance devices are commonly used in COPD; however, their efficacy is unclear and is inconsistent among cohorts.Objectives: This study aims to systematically review the evidence to determine the impact of airway clearance devices in patients with COPD.Methods: Databases for systematic reviews and published evidence were searched. Studies were included if they were randomized and compared an airway clearance device to usual care or control. Studies were required to report at least one of the following: exacerbations, sputum volume, hospitalizations, and health-related quality of life. Data were extracted and assessed for risk of bias, and outcomes were synthesized using RevMan.Results: Eighteen studies with available data were eligible for this review, totaling 855 participants. Airway clearance devices demonstrated significant improvements in sputum volume (-1.07 ml; -0.37 to -1.77). There were significant improvements in the rate of exacerbation frequency at 6 months (rate ratio, 0.50; 95% confidence interval, 0.30-0.83; P < 0.01). No significant improvement was noted for the Saint George's Respiratory Questionnaire (0.30; -1.56 to -3.41; P = 0.10) in stable patients. There was an improvement of -5.73 (-7.30 to -4.15) for the COPD Assessment Test and -1.72 (-2.85 to -0.59) for the Breathlessness Cough and Sputum Score (P < 0.01).Conclusions: Airway clearance devices can improve exacerbation frequency, sputum clearance, and symptoms in stable COPD. The evidence included in this review was predominantly low- to moderate-grade evidence.

Role of the active cycle of breathing technique combined with phonophoresis for the treatment of patients with chronic obstructive pulmonary disease (COPD): study protocol for a preliminary randomized controlled trial. Trials 2021; 22:228. [PMID: 33757568 PMCID: PMC7988997 DOI: 10.1186/s13063-021-05184-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2020] [Accepted: 03/11/2021] [Indexed: 11/16/2022] Open
Abstract
Background Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease characterized by coughing, the production of excess sputum, and dyspnea. Patients with excessively thick sputum may have frequent attacks or develop more serious disease. The guidelines recommend airway clearance for patients with excessive sputum who are hospitalized with COPD. The active cycle of breathing technique is the most common non-pharmacological airway clearance technique used by physiotherapists. However, the effectiveness of the technique is not always guaranteed. Active cycle of breathing techniques require the initial dilution of the sputum, usually by inhalation drugs, which may have limited effects. Recent studies have found that phonophoresis decreases inflammation, suggesting the potential of the combined usage of active cycle of breathing techniques and phonophoresis. Therefore, the aim of this study is to explore the effectiveness and safety of combining active cycle of breathing technique and phonophoresis in treating COPD patients. Methods and analysis We propose a single-blind randomized controlled trial using 75 hospitalized patients diagnosed with COPD with excessive sputum production. The patients will be divided into three groups. The intervention group will receive active cycle of breathing techniques combined with phonophoresis. The two comparison groups will be treated with active cycle of breathing techniques and phonophoresis, respectively. The program will be implemented daily for 1 week. The primary outcomes will be changes in sputum viscosity and production, lung function, and pulse oximetry. Secondary outcomes include the assessment of COPD and anxiety, measured by the COPD Assessment Test scale and the Anxiety Inventory for Respiratory Disease, respectively; self-satisfaction; the degree of cooperation; and the length of hospital stay. All outcome measures, with the exception of sputum production and additional secondary outcomes, will be assessed at the commencement of the study and after 1 week’s intervention. Analysis of variance will be used to investigate differences between the groups, and a p-value of less than 0.05 (two-tailed) will be considered statistically significant. Discussion This study introduces a combination of active cycle of breathing techniques and phonophoresis to explore the impact of these interventions on patients hospitalized with COPD. If this combined intervention is shown to be effective, it may prove to be a better treatment for patients with COPD. Trial registration The trial was registered prospectively on the Chinese Clinical Trial Registry on 24 December 2019.ClinicalTrials.gov ChiCTR1900028506. Registered on December 2019.

Abstract
BACKGROUND While active cycle of breathing technique for chronic obstructive pulmonary disease patients with more sputum can improve clinic outcomes, less is known about sputum viscosity and sputum production of the intervention. OBJECTIVE The purpose of our study was to explore the effect of active cycle of breathing technique on sputum viscosity and production among patients with chronic obstructive pulmonary disease. DESIGN This was a two-arms, parallel, randomized clinical trial. SETTING Study enrollment, randomization and implementation were conducted in the department of respiratory medicine inpatient at the Medical Center in Changchun, China. PARTICIPANTS Hospitalized patients due to chronic obstructive pulmonary disease who met additional eligibility criteria were randomized to active cycle of breathing technique (n = 50) or usual care group (n = 50). METHODS Patients in the intervention group received a week-long intervention from an experienced physical therapist. Patients in the usual care group received usual care as well as information and advice in the light of their health plan from respiratory medicine. The primary outcome was the changes on sputum viscosity and production. RESULTS Among one hundred patients who were randomized (mean [SD] age, 54.89 [12.06] years; females, 58%), ninety-six participants completed the study. No significant differences were found between two groups on the changes of sputum viscosity (t = 0.277, P = 0.782). And there were insignificant differences between groups in the average amount of sputum among 1 h (Z=-1.848, P = 0.065) and significant differences in the average amount of sputum among 24 h (Z=-2.236, P = 0.025). From admission to one week recovery, the changes in ratio of forced expiratory volume in 1 s to forced vital capacity (Z=-4.511, P<0.0001) and arterial oxygen saturation (Z=-2.997, P = 0.003) were better in active cycle breathing technique group. Total Chronic Obstructive Pulmonary Disease Assessment Test scale were similar among two groups (Z=-1.818, P = 0.069). No adverse events occurred during the study. CONCLUSION For patients with chronic obstructive pulmonary disease, active cycle of breathing technique can significantly result in sputum production and respiratory function, especially those of Global Initiative for Chronic Obstructive Lung Disease classification level 3, but did not result in the short-term improvement of sputum viscosity, quality of life and cost effectiveness.

Abstract
IntroductionOscillating positive expiratory pressure (OPEP) devices are intended to facilitate sputum clearance in chronic obstructive pulmonary disease (COPD), but there is uncertainty as to their place in treatment pathways. We aimed to review the existing literature to establish the evidence base for their use.MethodsA systematic search of records up to March 2020 was performed on PubMed, CINAHL, Medline (Ovid), Cochrane and Embase to retrieve clinical trials that evaluated the efficacy of OPEP devices in patients with COPD. Two independent reviewers retrieved the titles, abstracts and full texts, and completed the data extraction.ResultsFollowing full-text review of 77 articles, eight (six randomised control trials and 2 cross-over studies) were eligible for inclusion. Pooled analysis showed low-grade evidence that the use of OPEP devices was associated with decreased COPD symptoms and exacerbations (OR 0.37, 95% CI 0.19 to 0.72), and enhanced exercise capacity; 6 min walk distance (mean difference (95% CI), 49.8 m (14.2 m to 85.5 m); p=0.009]). However, studies were mostly short term with the majority having a high risk of bias. The average acceptance, completion and drop-out rates were 82%, 91% and 8%, respectively.ConclusionThe use of OPEP devices can have a positive impact in COPD, but confidence in effect sizes is low and there is a need for further, higher quality studies to examine their long-term efficacy in COPD as well as to identify specific patient phenotypes that are more likely to respond.PROSPERO registration numberCRD 42016041835.

Abstract
Objective To compare the effect of incentive spirometry with Acapella (Smiths Medical Inc, Carlsbad, California) in physiotherapy after coronary artery bypass surgery. Methods A randomized controlled trial comparing incentive spirometry with Acapella was conducted in the intensive care unit of Chaudhary Pervaiz Elahi Institute of Cardiology (CPEIC) Multan. The study began from December 2017 to August 2019 after getting approval from the ethical committee of the hospital. Informed written consent was taken from all 270 patients who were included in the study. Patients who underwent coronary artery bypass graft (CABG) were divided into two groups by the lottery method. The primary end-point of the study was to check the blood gases on Day 3 after the procedure at room air and compare it with the baseline and with blood gases immediately after the procedure. SPSS 23 (IBM Corp., Armonk, NY) was used to analyze the data of this study. For qualitative variables in data such as gender, place of living, patients with any comorbidities, and education status were statistically analyzed in percentage and frequencies. For numerical variables, such as age, body mass index, blood gases values, distance covered in a six-minute walk test, and spirometry values were analyzed and statistically measured as mean and standard deviation. A P-value of less than .05 was considered significant. Results The mean partial pressure of oxygen (PaO2) of incentive spirometry was 58.1±2.31 and 67.2±3.24 after extubation and after three days, respectively. While the PaO2 of Acapella was 56.3±3.43 and 66.4±3.54 after extubation and after three days, respectively. The mean PCO2 of incentive spirometry was 41.4±3.26 and 36.1±2.11 after extubation and after three days, respectively. While the partial pressure of carbon dioxide (PCO2) of Acapella was 39.4±2.55 and 37.5±3.58 after extubation and after three days, respectively. The differences were statistically significant at p-value ≤0.05. Conclusion It was concluded that both Acapella and incentive spirometry treatment after coronary artery bypass graft improved blood gases.

Abstract
OBJECTIVES Chronic obstructive pulmonary disease (COPD) is associated with a higher risk of pulmonary infections. This risk not only negatively affects patients' quality of life but also increases social and health costs. Hence, there is a need for an effective rehabilitative treatment including airway clearance. The aim of this pilot study was to evaluate the efficacy of a new tool for bronchial clearance based on expiratory flow accelerator (EFA) technology compared with positive expiratory pressure (PEP) treatment. MATERIALS AND METHODS Twenty stable patients with COPD, Global Initiative for Chronic Obstructive Lung Disease 3-4 stage, were enrolled and allocated to treatment with EFA or Bubble-PEP (BP) for 20 days during a pulmonary rehabilitation program. At baseline and the end of treatment, the following parameters were measured: arterial blood gases (ABG); respiratory function, including peak cough expiratory flow (PCEF), maximal inspiratory pressure (MIP), and maximal expiratory pressure exercise capacity using the 6-minute walk test (6MWT), dyspnea using the Medical Research Council scale, and quality of life using the St. George's Respiratory Questionnaire. RESULTS Expiratory flow accelerator showed a significant pre- and post-improvement in ABG and a significantly greater improvement than BP in PCEF, MIP, and 6MWT post-treatment. CONCLUSION Expiratory flow accelerator is a valid device compared with BP as an adjunctive therapy for the treatment of patients with severe COPD.

Oscillatory positive expiratory pressure (OPEP) devices have been utilized as an adjunct therapy to conventional chest physiotherapy (CPT) to promote the clearance of respiratory secretions in individuals with impaired ability to cough, particularly in chronic diseases. However, few studies have focused on the effectiveness of OPEP in lower respiratory tract infection. In the present study, all patients with lower respiratory tract infections hospitalized in the Department of Pulmonary and Critical Care Medicine, Ruijin Hospital (Shanghai, China) between February 2016 and July 2017 were analyzed. Daily sputum quantity and purulence were recorded on the first 7 days of physiotherapy. Oxygenation index, partial pressure carbon dioxide, white blood cell count, neutrophil percentage, C reactive protein (CRP) and procalcitonin (PCT) levels before and after CPT were compared between patients who received OPEP and patients who received mechanical percussion (MP). Sputum was collected prior to and following CPT. A total of 17 patients received OPEP, while 10 received MP. The OPEP group exhibited improved postural drainage compared with the MP group after 7 days of physiotherapy. After 7 days of CPT, patients who received OPEP also exhibited a significantly improved oxygenation index, while the oxygenation index in the MP group did not improve. The improvement of partial pressure carbon dioxide was not significantly different between groups. The OPEP group also exhibited a greater decrease in white blood cell count, neutrophil percentage and CRP levels, compared with the MP group. However, the decrease in PCT level was similar in the OPEP and MP groups. Sputum culture results revealed that the rate of negative conversion was very low in both groups. There was no difference between the two groups in terms of hospitalization outcomes. In conclusion, OPEP exhibited a greater effectiveness in draining sputum, improving oxygenation and reducing inflammatory status in patients with lower respiratory tract infections compared with MP; however, it did not promote the elimination of microbes.
