Efficacy of cardiopulmonary resuscitation performance while wearing a powered air-purifying respirator.

Abstract

BACKGROUND\nThe 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.\n\n\nMETHODS\nThis 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 period. 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\xa0min 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.\n\n\nRESULTS\nAll 34 participants completed the study. The sufficiently deep compression rate was 65.9\xa0±\xa031.1% in the 1-min shift group and 61.5\xa0±\xa030.5% in the 2-min shift group. The mean compression depth was 52.8\xa0±\xa04.3\xa0mm in the 1-min shift group and 51.0\xa0±\xa06.1\xa0mm in the 2-min shift group. These two parameters were significantly different between the two groups. There was no significant difference in the other values related to CPR quality.\n\n\nCONCLUSIONS\nOur findings indicated that 1\xa0min of chest compressions with a 1-min rest maintained a better quality of CPR while wearing a PAPR.
