Cardiac arrest & resuscitation
Ventilation rates measured by capnography during out-of-hospital cardiac arrest resuscitations and their association with return of spontaneous circulation
Authors' conclusion
We failed to detect an association between intra-arrest ventilation rates measured by continuous capnography and proximal patient outcomes after OHCA. Capnography has poor reliability as a measure of ventilation rate. Achieving guideline-compliant ventilation rates remains challenging.
Study context
- Population
- Adult non-traumatic out-of-hospital cardiac arrest (OHCA) with useable capnography data, over a two-year period790 OHCA analysed
- Participants
- 314 participants
- Exposure
- Ventilation rate measured by capnography and its association with return of spontaneous circulation (ROSC)
- Outcome
- Sustained prehospital ROSC
