[Possibility of the development of decompression sickness during testing of G suits]

This paper presents the results of 1179 altitude chamber tests of special suits performed by 193 subjects. The probability of altitude decompression disease observed during 29 experiments (2.5%) in 26 test subjects (13.4%) is calculated. The safety of decompression tables is evaluated as applied to the pressure 14-43 kPa after oxygen breathing for 0.25-2 hrs at sea level or for 1-6 hrs at 40 kPa.
