마네킨을 이용한 기관내삽관 시 백밸브마스크 양손하단 환기법의 효과

Abstract

Purpose: This study aimed to verify the effectiveness of the subjective ventilation method and the two-handed lower ventilation method in providing adequate ventilation. Methods: A total of 44 paramedic students participated in the experiment. The manikin used was the “BT-CSIE Airway Management Simulator.” The procedures were conducted using both the subjective ventilation method and the two-handed lower ventilation method. Ventilations were administered once every 6 seconds, for a total of 20 ventilations over 2 minutes. The average tidal volume per breath, ventilation time, and success rate were measured. All data were analyzed using IBM SPSS Statistics 27.0. Results: When comparing the effectiveness of the two methods, the average tidal volume was 408.53 ± 82.82 ml for the subjective ventilation method and 522.90 ± 30.32 ml for the two-handed lower ventilation method, showing a significant difference between the two (p < .001). The success rates were 16.36 ± 32.07 % and 73.75 ± 34.41 %, respectively, with the two-handed lower ventilation method demonstrating a significantly higher success rate than the subjective method (p < .001). Conclusion: Current guidelines do not specify a detailed method for delivering an adequate ventilation volume. This study confirmed that the two-handed lower ventilation technique can consistently provide an appropriate tidal volume.
