Cardiac arrest & resuscitation
Temporal analysis of continuous chest compression rate and depth performed by firefighters during out of hospital cardiac arrest
Authors' conclusion
A reduction in CC depth was observed during two-minutes of continuous CCs while CC rate was not affected. One third of patients received a mean CC depth within guideline range (50 to 60 mm).
Study context
- Population
- OHCA patients receiving continuous chest compressions by firefighters with cardiopulmonary resuscitation (CPR) feedback devices
- Participants
- 134 patients
- Outcome
- Chest compression depth and rate as a function of CPR duration
- Follow-up
- Two-minute episodes of CPR
Methodological detailsMean chest compressions (CC) depth and rate calculated every 5 s; regression models vs time
- Mean CC depth and rate calculated every 5 s; regression models vs time
