Cardiac arrest & resuscitation
A retrospective comparison of mechanical cardio-pulmonary ventilation and manual bag valve ventilation in non-traumatic out-of-hospital cardiac arrests: A study from the Belgian cardiac arrest registry
Authors' conclusion
Compared with MBV, CPV was associated with an increased risk of ROSC but not with improved an CPC score in patients with OHCA.
Study context
- Population
- Patients with non-traumatic Out-of-hospital Cardiac Arrest (OHCA), Belgian Cardiac Arrest Registry, January 2017–December 2021
- Participants
- 2,566 patients
- Exposure
- Mechanical cardio-pulmonary ventilation (CPV) vs manual bag ventilation
- CPVn = 298
- Manual bag ventilation (MBV)n = 2,268reference
- Outcome
- Return of spontaneous circulation (ROSC)
Methodological detailsregistry-based, two-level mixed-effects multivariable logistic regression
- Registry-based
- Two-level mixed-effects multivariable logistic regression
