加压供氧是飞机增压座舱在12公里以上高空发生迅速减压时的应急防护措施。为代偿加压呼吸的生理影响,英国空军自五十年代起,发展了“加压背心-抗荷服系统”(jerkin-type G-suit System),应用面罩加压供氧及躯干-下肢对抗加压,可保证17公里(56,000呎)的应急供氧,此时呼吸余压为60mmHg,肺内绝对压为115mmHg(Ernsting,1960)。该服装系统,热负荷较大。瑞曲空军用小的胸囊对胸部体表加
Pressurized oxygen supply is an emergency precaution when an aircraft booster cockpit is rapidly decompressed at a height of more than 12 kilometers. To compensate for the physiological effects of pressurized respiration, the British Air Force has developed the jerkin-type G-suit System since the 1950s, applying masks to pressurized oxygen and torso-lower extremities Opposing pressurization ensures an emergency oxygen supply of 17 km (56,000 ft), at which time the respiratory pressure is 60 mmHg and the absolute pressure in the lung is 115 mmHg (Ernsting, 1960).
