Purpose: Advanced airway maintenance improves the quality of cardiopulmonary resuscitation (CPR) for out-of-hospital cardiac arrest (OHCA) patients. In this study, we evaluate the factors associated with advanced airway management while performing CPR for out-of-hospital cardiac arrest patients by 119 emergency medical technicians (EMTs). Methods: The observational analysis method was used ro retrospectively collect data from 119 rescue run sheets. This study was conducted in a fire station in Seoul, Korea. The subjects of this study were defined as OHCA patients who received CPR from July 2016 to June 2018. We divided the subjects into two groups according to whether advanced airway maintenance was performed or not, and then compared and analyzed both groups. We performed logistic regression analyses for characteristics that differed significantly between groups. Results: Out of 188 OHCA patients, 146 (77.7%) had received advanced airway management. Statistically significant differences in the logistic analysis were found regarding the total number of EMT professionals (adjusted odds ration [aOR]: 1.955; 95% confidence interval [CI]: 1.227-3.115; p=0.005) and scene-time (aOR:1.119;95%CI:1.019-1.228;p=0.019). Conclusion: Advanced airway maintenance while performing CPR for OHCA patients by EMT associated primarily with ensuring an adequate numbers of EMT professionals and sufficient scene time.
