Two studies have documented that prehospital ventilation with the EOA, as measured by arterial blood gases, is inadequate.2,3One study used EMT II rescuers and the other paramedics, so training of rescuers does not appear to be important. Both studies indicated that difficulty in maintaining an effective mouth seal with the EOA contributed to the poor ventilatory results.2,3Facility of EOA insertion is a problem. The device offers little or no improvement over properly trained rescuers using endotracheal intubation. In a recent article in The Journal, Jacobs et al reported that the endotracheal tube was successfully placed
