Episode 10: Does using a small volume BVM affect ROSC?

Airway in Cardiac Arrest is still a bit of a mystery. We don't really know if we should intubate early. Contrary to prior studies showing no benefit of intubation over BVM or SGA, new evidence may be pointing in a different direction. We don't know the correct rate of breaths or volume of breaths or FiO2. Small animal studies and 'expert' opinion restrict our delivery of breaths to a maximum of 10 per minute and the volume of each breath to about 500 mL. This has resulted in some centres now using paediatric BVMs for adult resuscitation. Do these work? Previous studies may have shown no inferiority, but here is a new study, that suggests that traditional BVMs may be better.
