Automatic Ventilation in Prehospital Resuscitation on OHCA

Prehospital Automatic Ventilation on Resuscitation Outcomes in Out-of-hospital Cardiac Arrest Patients: a Randomized Controlled Trial

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.

Inclusion Criteria:

• Age over 18 years old at the time of occurrence of out-of-hospital cardiac arrest (OHCA).
• Attended by the Hsinchu County Fire Department for emergency medical assistance.

Exclusion Criteria:

• Pregnant women.
• OHCA caused by trauma.
• Return of spontaneous circulation (ROSC) observed at the scene.
• Clearly deceased at the scene (reaching conditions such as decomposition, rigor mortis, severe burns, decapitation, evisceration, or trunk fracture).
• Refusal of medical transportation by family members.
• No placement of an advanced airway throughout the procedure.
