Purpose: To provide information on the current state of cardiopulmonary resuscitation (CPR) performed by Korean paramedics in elevators and to identify effective chest compression methods when using a reduced stretcher in the confined space of an elevator. Methods: This study is designed to investigate the status of CPR in elevators, we compared the quality of manual chest compression and LUCAS3 mechanical chest compression device according to the angle change of the stretcher (0 degrees, 60 degrees, 85 degrees) using a mannequin in a model elevator. SPSS 22.0 was used to analyze the research data, the survey was analyzed using descriptive statistics, and the quality of chest compressions according to the stretcher angle was analyzed using t-test and ANOVA. Results: Mechanical chest compressions at 60° and 85° stretcher angles showed a more effective compression depth of 5-6cm than manual chest compressions, consistent with the CPR guidelines (p<.001). Additionally, mechanical chest compressions had a higher compression location accuracy than manual chest compressions (p<.05). There was no significant difference in the chest compression recoil rate between mechanical and manual chest compressions in the 60° and 85° stretcher positions. Conclusion: In confined elevator spaces, when the main stretcher was reduced and modified to angles of 60° and 85°, the mechanical chest compression device (LUCAS3) demonstrated superior consistency and efficiency in CPR quality compared to manual chest compression methods. This study highlights the need for standardized protocols and training.
