CPR compression depth and rate in relation to physical exertion in paramedic students

The purpose of this pilot study was to assess the level of work intensity and fatigue among undergraduate students during simulated CPR, including the quality of chest compressions. Methods: this was an observational pilot study investigating second year undergraduate paramedic students fatigue levels and quality of chest compressions following 20 minutes of simulated CPR. Data were collected at baseline and after every 2 minutes until conclusion of twenty minutes. Measurements of work intensity and fatigue included heart rate, rating of perceived exertion (Borg), compression depth and compression frequency. Results: a total of 7 subjects participated (2 male, 5 female), with five students aged 21-25 years. Male subjects showed a significantly slower compression rate when compared to females (108.0 vs 125.6 chest compressions per minute, P=0.006)
