Overview

The goal of this randomized controlled trial is to compare prehospital ventilation strategies in out-of-hospital cardiac arrest. The intervention group is automatic ventilation and the control group is manual ventilation. The main questions it aims to answer are:

1. How does automatic ventilation affect OHCA patients' survival and prognosis comparing to manual ventilation.
2. What are the differences on resuscitation qualities between automatic ventilation and manual ventilation.
