Acute cardiac care & resuscitationCohort study
Neurological outcome of out-of-hospital cardiac arrest patients ventilated with continuous flow insufflation of oxygen: a multicenter observational study
- multicenter observational cohort study
Authors' conclusion
The use of CFIO during OHCA was associated with significantly lower odds of favorable neurological outcome at day 30 compared to BVM.
Study context
- Population
- Adult patients from the Northern French Alps Emergency Network cardiac arrest registry who experienced OHCA in three different Emergency Medical Systems between 2017 and 2021
- Participants
- 2,237 included patients
- Exposure
- Continuous flow insufflation of oxygen (CFIO) versus bag-valve-mask ventilation
- CFIOn = 967
- Bag-valve-mask (BVM)n = 1,270reference
- Outcome
- Favorable neurological status according to the Cerebral Performance Category (CPC) scale (CPC 1 or 2)
- Follow-up
- 30 days
