Effects of forward-leaning cardiopulmonary resuscitation on chest compression quality and rescuer fatigue.

ABSTRACT:

Aim

Guided by the 2020 AHA quality targets for chest compressions, we used a manikin model to assess the effects of compression angle (90° vs. 100°) and audiovisual feedback on compression quality and rescuer fatigue.

Methods

This was a randomised, crossover, controlled trial. Four experimental groups were included: CCA90°, CCA90° with audiovisual feedback, CCA100°, and CCA100° with audiovisual feedback. Twenty-nine participants, following standardized training, performed 2-minute chest compression sessions on a manikin under each condition, with the order of scenarios randomized by lottery. Heart rate, blood pressure, and Borg Rating of Perceived Exertion (RPE) were recorded immediately before and after each session.

Results

Significant differences in mean chest comp
