Advanced Airway Device Use Order During Out-of-Hospital Cardiac Arrest

In this cross-sectional study, most patients with OHCA received ETI as the first advanced airway procedure, despite higher SGA first-pass success. Among patients whose initial attempt failed, most continued with the same device. However, switching from ETI to SGA had a higher final success rates. These findings highlight the importance of airway device sequence in prehospital care and may inform training and protocols for airway management.
