CPR quality reduced due to physical fatigue after a water rescue in a swimming pool

摘要

Objective. This study aimed to analyse the influence of physical fatigue, resulting from a simulated aquatic rescue, at aswimming pool, on the quality of cardiopulmonary resuscitation (CPR) delivered by the rescuer.Design, setting and participants. An intragroup design with 27 lifeguards was used in this study. The quality of CPR deliverywas evaluated for two minutes for all subjects while they were at rest (test 1), as well as after a simulated aquatic rescue ata swimming pool (test 2). A Resusci Anne® SkillReporter™ (Laerdal Medical Limited, Norway) manikin was used to retrievereports on CPR delivery, compliant with the most recent international guidelines (30:2, chest compression: ventilationratio).Results. Rescue-related physical fatigue had a significant influence on the total number of chest compressions as well as onthe ratio of correct chest compressions. Physical fatigue triggered by a swimming pool water rescue negatively influencedCPR delivery quality. These results show that the detrimental effects of physical fatigue on CPR delivery remain important,even in a swimming pool environment.Conclusions. Training programs should reflect this finding, and focus on enabling lifeguards to deliver proper CPR, evenwhile exhausted and for long periods of time.
