[Prevention of altitude decompression sickness during short flights in a depressurized cabin at high altitudes].
Forty altitude chamber experiments were carried out in which 18 test subjects participated. The purpose of the experiments was to prevent decompression sickness in a pilot using an altitude compensatory suit and oxygen mask. It was demonstrated that oxygen breathing on the ground and at an altitude of 8 km for 20 and 50-60 min eliminated severe symptoms and lowered the frequency of occurrence of mild symptoms of decompression sickness during the subsequent 10-20 and 60-120 min exposures to altitudes of 40,000 and 11,000 m respectively. An increase in the absolute pressure to 240-290 mm Hg in the altitude garment prevented decompression sickness of altitudes of 11,000-15,000 m and eliminated it if it occurred at lower barometric pressure.
