Abstract
The acceptable degree of hypoxia is a most important factor in design of pressure cabins and of aircrew oxygen breathing equipment. Studies of effects of mild hypoxia upon human performance performed since 1960 are reviewed. Hypoxia induced by breathing air at altitudes up to 5000 ft may be acceptable for crew and passengers of combat and passenger aircraft. The magnitude and effects of hypoxia induced by rapid decompression are considered. Results of experimental investigations are correlated, and the minimum acceptable alveolar oxygen tension on rapid decompression apparently is 30 mm Hg.
