The study suggests that 1 minute of chest compressions with a 1-minute rest maintained better CPR quality while wearing personal protective equipment.
ABS T R A C T Background: The use of personal protective equipment for respiratory infection control during cardiopulmonary resuscitation (CPR) is a physical burden to healthcare providers. The duration for which CPR quality according to recommended guidelines can be maintained under these circumstances is important. We investigated whether a 2-min shift was appropriate for chest compression and determined the duration for which chest compression was maintained in accordance with the recommended guidelines while wearing personal protective equipment. Methods: This prospective crossover simulation study was performed at a single center from September 2020 to October 2020. Five indicators of CPR quality were measured during the first and second sessions of the study pe-riod. All participants wore a Level D powered air-purifying respirator (PAPR), and the experiment was conducted using a Resusci Anne manikin, which can measure the quality of chest compressions. Each participant conducted two sessions. In Session 1, the sequence of 2 min of chest compressions, followed by a 2-min rest, was repeated twice; in Session 2, the sequence of 1-min chest compressions followed by a 1-min rest was repeated four times. Results: All 34 participants completed the study. The sufficiently deep compression rate was 65.9 + 31.1% in the 1-min shift group and 61.5 + 30.5% in the 2-min shift group. The mean compression depth was 52.8 + 4.3 mm in the 1-min shift group and 51.0 + 6.1 mm in the 2-min shift group. These two parameters were significantly dif-ferent between the two groups. There was no significant difference in the other values related to CPR quality. Conclusions: Our findings indicated that 1 min of chest compressions with a 1-min rest maintained a better qual-ity of CPR while wearing a PAPR. (c) 2021 Elsevier Inc. All rights reserved.
