pressure breathing

A method of compensating for the reduced partial pressure of oxygen caused by an increase in altitude. At cabin altitudes above 40,000 ft, the atmospheric pressure is so low that even 100% oxygen fails to prevent tissue hypoxia. Oxygen is pumped into the lungs at a positive pressure to enable the blood to absorb it in the required quantities. Normally, a pressure suit and/or a pressure mask is used in conjunction with pressure breathing. See also pressure suit.

A feature of the early positive pressure breathing devices, which were used variously as IPPB machines as well as continuous ventilators, was that they typically included a high pressure gas source for powering the nebulizer.

The system combines two features: positive pressure breathing (PPB) via an oronasal mask, which delivers oxygen into the lungs under pressure, and simultaneous counterpressure to the torso and lower limbs, applied by inflatable bladders in a chest jerkin and an anti-g suit (Sharp & Ernsting, 1988).
