Purpose: This study aimed to compare the effects of rescue ventilation maneuvers on the quality of two-rescuer cardiopulmonary resuscitation (CPR). Methods: We implemented mouth to mouth (MMV), mouth to pocket mask (MPV) and bag-valve mask ventilation (BMV) maneuvers. Each team of two-nurses was randomized to perform three consecutive sessions of two-rescuer CPR by using three artificial ventilation maneuvers. Results: The subjects were 26 teams of nurses (female: 96.2%, male: 3.8%, age: 26.6 years). Failed ventilation was more frequent in BMV (2.23±2.21, p ＜.001) than MMV (0.31±0.74) and MPV (0.38±0.64). BMV had more compressions per minute (93.7±5.7) than MMV (87.0±7.2, p = .001) and shorter total compression pause time (46.1±5.8sec) and compression pause fraction (23.3±2.2%) than MMV (54.8±10.3sec, p = .001, 25.5±3.5%, p = .001, respectively) and MPV (53.1±7.1sec, p = .006 and 25.8±2.6%, p = .006, respectively). Conclusion: In our simulation study, BMV reduced the compression pause time and increased the number of compressions per minute, thus indicating CPR provided to patients was effective. However, considering the high rate of ventilation failure, we recommend periodic training.
