title: [Human gas exchange at +Gz with the use of various anti-g protectors].
abstract: Human respiration parameters were studied in subjects exposed to +Gz (6.0; 7.0, 8.0 and 9.0 g with a 15-s plateau and a g-gradient of 1.0 and 5.0 g/s) with the use of anti-g measures, i.e. a barber chair inclined at 30 or 45 degrees, anti-g suit VKK-15 with a pressure controller, and a positive oxygen pressure. The gas-exchange parameters were found to be indicative of the effectiveness of an anti-g protector. When used together, these protective methods (VKK-15 munitions, an oxygen respirator for positive-pressure breathing, and chair back inclination to 45 degrees) improved g-tolerance significantly.
