[The possibility for the pilot to recognize hypoxia in a high-altitude flight]

The article studies the possibility of man to self-diagnose the development of hypoxia and take decisive actions on its elimination with the help of flight living facilities. Four variants of hypoxia were modeled at hyperbaric chamber and flight simulator. The differences between these four variants were the following: strength, increase velocity and duration of hypoxia, the level of "notification" about the oxygen conditions for tested persons. The authors make a conclusion that man is capable of discovering hypoxia both at rest and active operating state, that gives the possibility to take an adequate decision on coming out from critical situation caused by hypoxia.
