Abstract

|
|
Purpose: We conducted this study in order to evaluate the question of whether a simple voice prompt, “push hard and fast”, could improve the quality of chest compression performed by lay people.
Methods: Non-medical college students with no experience of cardiopulmonary resuscitation (CPR) education participated in this study. They were randomly divided into two groupsmetronome prompt automated external defibrillator (AED) (M) group and metronome with intermittent “push hard and fast” voice prompt AED (V) group and performed two cycles of chest compression-only CPR. “Push hard and fast” voice was prompted every 10 seconds. The rate of metronome was fixed to 100/min in two groups. We measured compression depth, compression rate, and total compression frequency using ResusciAnne SkillReporterTM (Laerdal, Korea).
Results: A total of 208 volunteers were enrolled. There were 120 (57.7%) females, and mean age was 21±2 years old. The compression depth was deeper in the V group (40.0± 12 mm) than in the M group (35.9±13 mm) (p=0.02). The mean rate of chest compression was faster in the V group (98±20 cpm) than in the M group (88±31 cpm) (p=0.07) (*cpm: compressions per minute). Total frequency of chest compression during 2-cycle CPR was also higher in the V group (392±80) than in the M group (341±117) (p<0.001).
Conclusion: A simple voice prompt, “push hard and fast”, can improve the quality of chest compression performed by untrained lay people.
