[Maintenance of vitality and performance of pilots by means of oxygenation equipment complex in emergency depressurization of the cabin].

The authors studied efficiency of life supply by means of Oxygenation Equipment Complex (OEC) for pilots subjected to depressurization of the cabin in emergency on altitudes under 20 km. OEC provides breathing under the excessive oxygen pressure and light-weight ammunition. Efficiency of the complex was evaluated through polling the examinees, the time of the discomfort occurrence, changes of the cardiorespiratory and visual parameters, functional tests and quality of the piloting. The studies proved OEC to be effective means for saving the life and the performance maintaining when the depressurization of the cabin on altitudes under 20 km. The authors estimated "reserve time" for the pilot's performance maintaining within the altitudes of 14-16-18-20 km and revealed the factors delimiting efficiency of OEC in the studied conditions.
