It was intended to present a training method so that high-quality cardiopulmonary resuscitation (CPR) can be performed by analyzing chest compression according to differing support surfaces. 33 participants did 150 chest compressions based on the adult CPR in the conditions of hard floor, bed, bed with backboard, ambulance stretcher, and ambulance stretcher with backboard by using manikin. 165 manikin assessed scores were collected and compression depth, compression rate, incorrect pressure point, incomplete recoil, and chest compression correctness were analyzed by using one-way ANOVA. The compression depth in all participants was a statistically significant difference (p<.001), and the difference between the hard floor and the other surfaces was confirmed. The compression rate in all participants was a statistically significant difference (p<.001), and the difference between the hard floor and the bed & bed with backboard was confirmed. The compression correctness in all participants was a statistically significant difference (p<.001), and there was the hard floor (93.2%), bed (67.8%), bed with backboard (66.8%), ambulance stretcher (9.0%), and ambulance stretcher with backboard (7.8%). To perform correct depth, correct pressure point, and complete recoil accordance with the American Heart Association (AHA) guidelines, chest compression on the floor must be performed.
