Cardiac arrest & resuscitation
Factors associated with cardiopulmonary resuscitation (CPR) quality in out-of-hospital cardiac arrest
Authors' conclusion
This study identified prehospital factors associated with improved CPR quality, including the involvement of fire-fighter first responders, highlighting their vital role in the emergency medical response.
Study context
- Population
- Adult medical out-of-hospital cardiac arrest (OHCAs) with attempted resuscitation involving >2 min of CPR, Victorian Ambulance Cardiac Arrest Registry, 2019–2025
- Participants
- 9,174 participants
- Outcome
- CPR quality: % compressions at target depth (50-100 mm), % at target rate (100-120/min), compression fraction ≥90 % and mean release velocity
