The aim of the study is to measure the quality of cardiopulmonary resuscitation (CPR) and the fatigue of rescuers wearing PPE (Level D) during a CPR session and to ultimately provide suggestions of safety standards for rescuers.
36 subjects were enrolled in the study. The subjects were divided randomly into three groups of two-members, three-members, and four-members. Each group performed CPR for 30 minutes. Blood lactate concentration, heart rate, rating of perceived exertion, chest compression depth and rate were measured before experiment and after each cycle.
There was a difference in the blood lactate concentration during CPR cycle by member of shifts (p=.014). The blood lactate concentration increased during CPR (p=.000). Subjective fatigue was a significant difference of chest compression in cycles 3, 4, and 5 for the member of shifts during CPR (p=.049, p=.009, p=.015). Depth and rate of chest compression were not different for the member of shifts during CPR.
It is necessary to establish standards for the member of shifts during CPR, to reduce the fatigue of rescuers.
