title: Evalution of mechanical ventilators in a hyperbaric environment.
abstract: Four mechanical ventilators, the pneumatic Emerson, IMV bird, Urgency bird, and the Modified Mark 2 bird were tested in a hyperbaric chamber at depths up to 165 ft of sea water (FSW). All failed except the Emerson, which is the only machine recommended for chamber use at this time.
