Cardiac Arrest Resuscitation: Passive Oxygen Flow Better Than Assisted Ventilation

Arizona researchers compared the survival rates in out-of-hospital cardiac arrest patients treated with positive-pressure ventilation (bag-valve mask) vs. passive oxygen flow. Survival was higher (38.2 percent) with passive oxygen flow than with assisted ventilation (25.8 percent). This study reinforces the notion that survival of out-of-hospital cardiac arrest might have more to do with circulating the blood through uninterrupted chest compressions than with ventilation.
