Arizona researchers find passive oxygen flow better than assisted ventilation

[Source: ScienceDaily] – Arizona researchers have added another piece to the mounting body of evidence that suggests during resuscitation efforts to treat patients in cardiac arrest, “passive ventilation” significantly increases survival rates, compared to the widely practiced “assisted ventilation.”

The study, published in an online edition of Annals of Emergency Medicine, compared the numbers of patients who had suffered a cardiac arrest outside a hospital setting and were resuscitated in the field by Emergency Medical Services personnel. Rescuers used either bag-valve-mask ventilation, which forces air into the patient’s lungs, or facemasks with a continuous flow of oxygen, which work in a similar fashion to those carried on airplanes in case the cabin pressure drops.
