Quantitative Analysis of Bystander Cardiopulmonary Resuscitation Quality

Abstract

PURPOSE The purpose of this research was to investigate the effects of gender and number of rescuers on the quality of cardiopulmonary resuscitation (CPR). METHODS Fifty-five university students (23 males vs. 32 females) participated in this study voluntarily. Each subjects performed one rescuer CPR and two rescuer CPR for 5-cycles in random order. The quality of CPR was recorded using a Resusci Anne Skillreporter manikin. RESULTS Male participants presented higher compression depth and correct compression than females. Two rescuer CPR had higher compression depth and correct compression than one rescuer CPR, but the two rescuer CPR had lower hands off time and compression fatigue. There was a significant gender by number of rescuers interaction for a compression rate. The two rescuer CPR had higher numbers of ventilation, but lower ventilation fatigue compared with the one rescuer CPR. There was a significant correlation between compression fatigue and compression depth of female subjects. CONCLUSIONS These results suggest that laypersons are taught to perform two rescuer CPR to provide high quality CPR. To increase the number of people trained in CPR, CPR educational program should be included in an undergraduate curriculum.
