Abstract

Purpose: Maintaining the quality of CPR is connected with improvement in survival rates, but CPR performance in the field does not always fulfill the guidelines. Therefore, many ways to obtain the quality of CPR have been studied and tried, including CPR education, manikin training, mechanical CPR, audio-visible feedback system, and video-recording system, et cetera. The aim of our study is to determine how CPR procedures are actually performed on the scene by real-time video recording.
Method: Digital video of CPR cases was obtained from April 2014 to March 2015 in a wide regional emergency medical center. The video was analyzed by two physicians in the emergency department. We evaluated quality of major CPR variables including compression rate, hands-off time, chest compression fraction, ventilation rate, et cetera.
Results: A total of 52 cases were analyzed. Mean chest compression rate was 122.43±10.74/min, and mean ventilation rate was 7.47±2.58/min. Performance of adequate compression-to-ventilation ratio before insertion of advanced airway was 37%. Mean recognition to compression time was 31.31±27.32 seconds, and proportion of chest compression interruption time exceeding 10 seconds was 7.6%. Mean chest compression fraction was 91.12±0.4%. In five out of 25 cases of defibrillation, chest compression was interrupted during charging, resulting in prolongation of chest compression interruption time.
Conclusion: In this study, overall performance met the qualification of AHA guidelines. However, poor compliance was observed for some parameters. Continuous education and feedback are required in order to make an improvement in these areas.
