Abstract

Purpose: This study aimed to identify effective cardiopulmonary resuscitation methods by comparing the fatigue of rescuers according to various positions in cardiopulmonary resuscitation situations conducted on beds in hospitals.
Methods: An experimental study of students in the department of emergency medical service in H University, G Metropolitan City was conducted in four positions for applying chest pressure on mannequins on beds.
Results: As a result of measuring the muscle fatigue of four muscle attachments according to the four positions conducted on the bed, the average was 3.4%, the P was significant at 0.001, and the fatigue difference was confirmed to occur depending on the attachment. An analysis of pressure depth by pose revealed that P1, P2, P3, and P4 have a depth of 58.3, 55.1, 56.4, and 56.3 mm, respectively, with P4 having the deepest depth.
Conclusion: Among the various postures of the rescuer during cardiopulmonary resuscitation performed on the bed in the hospital, P1 is thought to be the most tiring, although its associated CPR quality is good.
