Abstract
Purpose : Inadequate chest compression during cardiopulmonary resuscitation(CPR) may result in the insufficient blood flow to preserve critical organ function. The study evaluated changes of quality of cardiopulmonary resuscitation over time in 30:2 CPR by laypersons and analyzed rescuer factors affecting the quality of chest compressions over time. Methods : This study was designed to know quality of CPR changes during 5 minutes. 47 students completed CPR training courses. They were performed 30:2 CPR using a manikin with Skill-Reporter for 5 minutes continuously to get data of depth, rate of chest compression, volume and correct rate of ventilation. Results : Time dependent analysis showed significant ineffective compression depth in females and under weight rescuers. In case of female, we found effective compression depth has maintained up to 2 minutes, but it decreased significantly after 2 minutes. However, underweight rescuers maintained effective compression depth up to a minute but it decreased after 1 minute. Conclusion : Although compression rate maintained over time, chest compression quality declined significantly. It suggested switching compression at an interval of 2 minutes is reasonable for 30:2 CPR by layperson but underweight rescuers may provide effective chest compression by switching shift every one minute.
