What does this research mean for the field?

Physical exertion and acute stress exposure prior to initiating cardiopulmonary resuscitation significantly reduce overall CPR quality and compression scores in active firefighters. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

This study aims to understand how physical and psychological stress before cardiopulmonary resuscitation affects performance in firefighters.

Implication

Field study investigates the impact of pre-resuscitation exertion on CPR performance in firefighters, revealing potential quality declines.

Key Points

This study aims to understand how physical and psychological stress before cardiopulmonary resuscitation affects performance in firefighters.
Within-subject field design with 23 firefighters participating.
Participants performed CPR on a manikin before and after performing a demanding fire service task.
Physiological markers such as cortisol and alpha-amylase, along with self-reported measures, were assessed.
Cortisol levels increased by 236% (95% CI: 56–416%, p < .001) after exertion.
CPR quality declined overall by 24% (95% CI: 12–36%, p = .002, r = .81) and compression scores by 36% (95% CI: 18–55%, p = .001, r = .81).
Results suggest pre-resuscitation exertion leads to reduced CPR performance quality.
