DEVELOPMENT OF ORAL-NASAL MASKS, OXYGEN, MC-1 AND MBU-5/P
Abstract
A small, lightweight, nonfreezing, oral-nasal pressure-breathing oxygen mask for use at altitudes to 45,000 ft was developed. The program covered two masks, the single-size MC-1 mask and the four-size MBU-5/P mask. The one-size mask would not accommodate a large enough segment of the Air Force flying population. Pilots enthusiastically indorsed the MBU-5/P ask. Each mask has a single, pressure-compensated, inhalation-exhalation valve as well as provision for a small, lightweight, noise-suppressing microphone. A single-strap, self-oriented harness requiring only one buckle for adjustment was developed. An altitude-compensating, harness tension system and a quick- donning mask harness are described.
