Abstract
OBJECTIVE We evaluated the quality of 2-minute continuous chest compressions (CCCs) performed by emergency staff in 30-second intervals to determine the effect of a feedback system on maintaining the quality of CCCs. METHODS Two hundred three physicians and nurses were randomised into two groups. Each participant performed 2-minute CCCs both with and without feedback. Group A performed CCCs under the guidance of a feedback device followed by performance without feedback, and Group B performed these tasks in reverse order. The primary outcome was the proportion of optimal compressions; i.e., compressions at both the correct rate (100-120 beats/minute) and correct depth (5-6 cm). RESULTS During 2-minute CCCs, the proportion of optimal compressions was poor in personnel without feedback. The proportion of optimal compressions was unchanged and low from 2.4% (interquartile range, 0.0%-32.8%) in the first 30 seconds to 3.3% (0.0%-47.7%) in the last 30 seconds of the 2-minute period. Use of the feedback device significantly improved and maintained the quality of compressions from the first 30 seconds (53.3%; 29.2%-70.4%) to the last 30 seconds (82.8%; 50.8%-96.2%). CONCLUSION Use of the feedback device was helpful for maintaining the quality of CCCs.
