Psychophysiological aspects of human adaptation to prolonged uninterrupted stay in a fireproof artificial gas environment
Human exploration of space and ocean ultimately involves the development of loop ecological systems - hermetic objects that provide human activity in different environments. One of the main tasks of artificial ecological systems is to maintain human health and performance along with increased safety of a loop system, especially its fire safety. In recent decades, artificial atmospheres with low oxygen content are believed to be an optimal solution. However, decreased volume of oxygen in the environment leads to hypoxia in people working within such an object. Replacement of the oxygen volume with indifferent gases could be a compromise solution. But up to now, there are no convincing data about influence of such gas environment on working capacity and functional condition of humans. This article presents findings obtained during 60-day continuous stay of humans in the normobaric hypoxic environment (О2 14 %, Ar 35 %).
