Dear Editor,
I read the article by Skulec et al. “Rescuer fatigue does not correlate to energy expenditure during simulated basic life support,” with great interest. (1) Although conventional cardiopulmonary resuscitation (CCPR) has been considered a standard CPR method since 1960, compression-only CPR (COCPR) has emerged as an alternative method to CCPR because of some evidence favoring COCPR. (2,3)
Therefore, numerous studies have attempted to determine whether COCPR could indeed improve the quality of CPR. A systematic review of these studies confirmed several obvious differences. (4)
