Abstract

Objective: Clinical studies have shown that eliminating performer errors is important to ensure high quality cardiopulmonary resuscitation (CPR). Literature on the effects of metronome use on the quality of CPR is scarce. This study aimed to investigate the effect of metronome use on the quality of cardiopulmonary resuscitation. Methods: Thirty volunteer emergency physicians who were divided into 15 groups participated in this prospective, observational, multi-center, manikin study. Firstly, each participant performed conventional CPR on a manikin, and then performed metronome-guided CPR after a short break. Parameters affecting CPR quality were evaluated based on the recommendations of the 2015 American Heart Association CPR and Emergency Cardiovascular Care Guideline. In addition, the fatigue levels of participants were evaluated using the Borg Fatigue Index. Results: Metronome-guided CPR significantly improved the chest compression rate (median (Interquartile Range-IQR); 128 (22) compressions/min vs. 110 (2) compressions/min; 95%CI, p < 0.001), deep compression rate (median (IQR); 95.25 (80) compressions/min vs. 72.63 (105) compressions/min; 95%CI, p < 0.001), compression depth (median (IQR); 62.50 (11) mm vs. 60.25 (14) mm; 95%CI, p = 0.016), ventilation number (median (IQR); 11.25 (6) ventilations/min vs. 9.50 (1) ventilations/min; 95%CI, p = 0.001), high-volume ventilation count (median (IQR); 10.13 (6) ventilations/min vs. 9.50 (1) ventilations/min; 95%CI, p = 0.026), minute ventilation volume (median (IQR); 11.75 (10) L/min vs. 8.03 (3) L/min; 95%CI, p < 0.05), and fatigue levels (median (IQR); 3 (2) vs. 2 (2); in 95%CI, p < 0.05). Conclusions: Our study showed that metronome is a useful device for reaching effective CPR. Metronome guidance may change the CPR parameters positively. This study is in accordance with previous studies which have investigated the effect of metronome-guided CPR on survival.
