PG - 51-55 LID - 10.4103/2452-2473.309137 [doi] AB - OBJECTIVE: Whether the use of metronome affects the quality of cardiopulmonary resuscitation (CPR) remains unclear. In this study, we investigated the effect of metronome use on CPR quality. METHODS: This was a prospective, simulation-based CPR manikin study. There were two phases: without and with metronome use. Chest compression was performed for 2 min, and three CPR quality criteria including chest compression depth, recoil, and rate were recorded with TrueCPR Feedback Device in both phases. RESULTS: In all, 102 resident physicians were included. The achievement of optimal chest compression depth and complete recoil was better with metronome use than without (83% and 77% vs. 78% and 39%, P
