Background: Out-of-hospital cardiac arrest due to hypoxia, it is necessary to provide adequate oxygen for correction of the cause. So, the purpose of this study was to compare the overall quality of CPR, willingness to perform ventilation using ventilation aids, and self-efficacy compared to the enlisted ventilation method (MMV) by educating the general public on pocket masks (MPV), which are respiratory aids. 

Methods: This study was a randomized controlled comparative study, in which 110 study subjects were listed with numbered names in the order in which they applied for training, and random numbers were named A (MMV method) and B (MPV method) in that order. Randomization generated a random number order using the SAS program, and the generated random numbers A and B were arranged from 1 to 110 in the order in which they applied for training, through this, they were classified into A groups (N = 57) and B groups (N = 53). The study subjects classified into Group A received CPR training including enlistment ventilation on April 22, 2023, and the trainees in Group B received CPR training using a ventilator on April 29, 2023. 

Results: The primary outcome is that the result of the comparison of ventilation quality is the mean Tidal Volume (TV) before training for MPV is 1076 ± 422, whereas the mean TV for MMV is 1015 ± 510 (p < 0.05). After training, the mean tidal volume (TV) for MPV is 876ml ± 422, whereas the mean TV for MMV is 1001 ± 516, indicating that MMV resulted in a significantly higher tidal volume than the ILCO guidelines. After training, comparing the time per ventilation cycle, the MPV group showed 0.923sec ± 0.432, while the MMV group showed 1.021sec ± 0.535 (p < 0.05). After completing two ventilations, it is evident that there is a delay in starting the next chest compression in the MMV group compared to the MPV group (MMV: 10.21 ± 4.112 vs. MPV: 9.88 ± 2.831, p < 0.05). 

Conclusion: As a result of this study, the researcher recommends adding training on pocket masks when educating artificial respiration in CPR training conducted in Korea, given that the performance accuracy of pocket masks is high and the efficient ventilation rate is high.
