CPR PRO® device reduces rescuer fatigue during continuous chest compression cardiopulmonary resuscitation: a randomized crossover trial using a manikin model

Background: The performance of high-quality chest compressions with minimal interruptions is one of the most important elements of the "Chain of Survival."

Objectives: To evaluate the impact of a novel CPR PRO(®) (CPRO) device for manual chest compression on rescuer fatigue, pain, and cardiopulmonary resuscitation (CPR) quality.

Methods: Randomized crossover trial of 24 health care professionals performing continuous chest compression CPR for 10 min with a CPRO device and conventional manual CPR (MCPR). Data about chest compressions were recorded using a manikin. Rescuers' physiologic signs were recorded before and after each session, and heart rate (HR) data were tracked continuously. Fatigue was assessed with ratings of perceived exertion, and pain questionnaire.

Results: All subjects completed 10 min of CPR with both methods. Significantly more rest breaks were taken during MCPR sessions (1.7 ± 2 vs. 0.21 ± 0.72). Subjects' perceived exertion was higher after MCPR, as well as the average (120.7 ± 16.8 vs. 110.8 ± 17.6) and maximal HR (134.3 ± 18.5 vs. 123.42 ± 16.5) during testing. Subjects reported more pain in the hands, especially the wrist, after performing MCPR. Average depth of compressions was higher with the CPRO device (4.6 ± 7.0 vs. 4.3 ± 7.9) and declined more slowly over time. Other CPR quality parameters, such as the correct position and complete release of pressure, were also better for CPRO CPR.

Conclusions: CPRO device reduces rescuer fatigue and pain during continuous chest compression CPR, which results in a higher quality of CPR in a simulation setting.
