Abstract
Physical characteristics of the earth's atmosphere are discussed and related to human physiological processes involved in problems of high altitude flight. Physical characteristics include composition of the atmosphere, atmospheric pressure at various altitudes, partial pressures, respiratory functions and respiratory gas levels, and respiration. Hyperventilation, hypoxia, and the bends are discussed in terms of the physiological processes. Data are given on the symptoms of hypoxia correlated with altitude and time of exposure, time of useful consciousness, expansion ratios of trapped gas in body fluids, oxygen dissociation curves for human blood, and blood oxygen saturation correlated with alveolar oxygen partial pressure and altitude. Also included are eardrum tension, respiratory infections and nasal sinuses during changes in atmospheric pressure. (Contract No. 210-76-0118)
