Is bag-mask ventilation during out-of-hospital cardiorespiratory arrest noninferior to endotracheal intubation for favorable neurological outcome?

BEEM Bottom Line

Why is this study important?

This is the first large randomized controlled trial (RCT) to evaluate bag-mask ventilation (BMV) compared with endotracheal intubation (ETI) in cardiac arrest patients. ETI is considered a definitive airway, but it is difficult to perform without a pause in compressions, which is associated with poorer outcomes. This study focused on a patient-oriented outcome of favorable neurological function at 28 days.

Which, if any, threats to validity are most likely to have an impact on the results and how?
