Purpose: This study aimed to analyze changes in the quality of cardiopulmonary resuscitation (CPR) performed by lifeguards before and after high-intensity rescue swimming and to identify associated physiological and subjective fatigue responses. The findings provide evidence to enhance practical, field-oriented lifeguard training and education. Methods: A single-group pretest–posttest design was conducted with 19 certified lifeguards between June 15 and July 25, 2025. Participants performed CPR for five minutes both before and after a standardized rescue swimming task. CPR quality indicators and physiological responses were compared using paired t-tests and repeated-measures ANOVA. Results: After rescue swimming, the total number of chest compressions increased significantly (p = .024), while the number of correct compressions (p < .01), compression accuracy ratio (p < .05), and full chest recoil ratio (p < .001) decreased. The overall compression score also declined (p < .05). Although ventilation quality did not significantly change, correct ventilations decreased from 61.1% to 48.7%. Mean tidal volume exceeded the American Heart Association guideline (500-600 ㎖) both before and after swimming, indicating hyperventilation. Physiological indicators showed significant increases in heart rate, end-tidal CO₂, and systolic blood pressure, whereas oxygen saturation (SpO₂) and diastolic blood pressure decreased. Subjective fatigue scores were significantly higher immediately after the rescue swimming compared to those recorded after performing CPR following the rescue swimming (p < .001). Conclusion: Rescue swimming induced acute physiological stress and fatigue, leading to a decline in CPR quality, particularly in compression accuracy and chest recoil. The presence of hyperventilation suggests the need for enhanced ventilation control training. Integrating high-intensity, field-simulated practice into lifeguard education is essential to sustain optimal CPR performance in real-life rescue scenarios.

소개
복합 구조적인 산업사회의 발전에 따라 안전사고와 응급상황에서의 구조구급요청자들이 증가하고 있으나 우리나라의 응급의료체계는 아직 그 수준을 따라가지 못하고 있는 실정이다. 이에 우리나라의 응급의료체계를 확립하고 구조구급에 관한 기초학문의 발전에 기여하고자 학회를 창립한다.
