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.

Objectives: Given that cardiopulmonary resuscitation (CPR) is an aerosol-generating procedure, it is necessary to use a mechanical ventilator and reduce the number of providers involved in resuscitation for in-hospital cardiac arrest in coronavirus disease (COVID-19) patients or suspected COVID-19 patients. However, no study assessed the effect of changes in inspiratory time on flowrate and airway pressure during CPR. We herein aimed to determine changes in these parameters during CPR and identify appropriate ventilator management for adults during CPR.Methods: We measured changes in tidal volume (Vt), peak inspiratory flow rate (PIFR), peak airway pressure (Ppeak), mean airway pressure (Pmean) according to changes in inspiratory time (0.75 s, 1.0 s and 1.5 s) with or without CPR. Vt of 500 mL was supplied (flowrate: 10 times/min) using a mechanical ventilator. Chest compressions were maintained at constant compression depth (53 ± 2 mm) and speed (102 ± 2/min) using a mechanical chest compression device.Results: Median levels of respiratory physiological parameters during CPR were significantly different according to the inspiratory time (0.75 s vs. 1.5 s): PIFR (80.8 [73.3 – 87.325] vs. 70.5 [67 – 72.4] L/min, P < 0.001), Ppeak (54 [48 – 59] vs. 47 [45 – 49] cmH<sub>2</sub>O, P < 0.001), and Pmean (3.9 [3.6 – 4.1] vs. 5.7 [5.6 – 5.8] cmH<sub>2</sub>O, P < 0.001).Conclusions: Changes in PIFR, Ppeak, and Pmean were associated with inspiratory time. PIFR and Ppeak values tended to decrease with increase in inspiratory time, while Pmean showed a contrasting trend. Increased inspiratory time in low-compliance cardiac arrest patients will help in reducing lung injury during adult CPR.
