Abstract P154: The Effects of ‘Hands-only Cardiopulmonary Resuscitation (CPR)’ in CPR Education in School
Introduction: The success of cardiopulmonary resuscitation (CPR) depends on rapidity of intervention and quality of CPR. The American Heart Association (AHA) has recently recommended ‘Hands-only CPR’, without ventilation, for bystander rescuers. In the present study, we investigated the educational effects of ‘Hands-only CPR’ in elementary school students. We further analyzed this variable on CPR skill learning and retention ability immediately after education.
Hypothesis: ‘Hands-only CPR’ is easy to learn and permits good skill retention immediately after education.
Methods: We selected two groups of 5th grade elementary school students to perform this study. One group has received CPR education with ventilation (CPR with ventilation group), while the other has received hands-only CPR education (hands-only CPR group). Laerdal PC SkillReporting system was used for both education and evaluation immediately after. Skill performance data, together with ventilation data and compression data were registered for further comparison.
Results: There were no differences in height and weight between two groups (141.5±6.6 cm vs 141.7±6.3 cm in height, 40.5±9.7 kg vs 38.8±9.0 kg in weight). Chest compression had no differences in average rate, average duty cycle, registered with no error, average depth etc. between two groups (table⇓). Average count per minute was 117±12/min in hands-off CPR group compared to 85±13/min in CPR with ventilation group (p=0.001). Registered adequate compression depth was 29±38 in hands-only CPR group and only 18±25 in CPR with ventilation group (p=0.018). The total hands off time was 18±7 seconds in ‘Hand-only CPR’ group in contrast to 40±11 seconds in CPR with ventilation group (table⇓).
Conclusion: The ‘Hands-only CPR’ in elementary school children increased chest compression rate and adequate compression depth. Moreover, ‘Hands-only CPR’ decreased hands off time during CPR.
