A C-shaped bend is prevalent in long, thin fingers when administering the two-finger compression technique in infant cardiac arrest, making vertical chest compressions difficult. This study was a mannequin experiment, which investigated the effect of grip and back muscle strengths on the outcome of infant chest compressions. Twenty 4th year paramedicine students who had completed 15 weeks of cardiopulmonary resuscitation (CPR) training were recruited as subjects in this study. The results demonstrated greater grip strength in men than in women. Additionally, grip strength, height, and sex were found to have significant correlations with the depth of chest compressions. The chest compression depth decreased over time, using the two-finger compression technique, while the rate of incomplete release increased. Grip strength was observed to affect the ability to maintain compression depth over time, demonstrating the need for a program to improve basic fitness.
