前言 在飞船舱外零重力下活动的宇航员的减压病与在地面同R值的测试比有明显的减少。为了研究这一点,采用椅形支架模型在低压舱模拟微重力状态下,对受试者进行了减压。方法 志愿者歇于椅中共6h,后4h为预吸O_2期。受试者在预吸O_2期间既可轻微活动(25W)也可保持安静。接着在低压舱中于歇于座椅位置,减压到30000英尺(9144m)3h。这些歇在座椅中预吸氧的受试者,和他们自身在高空的另一处
INTRODUCTION There is a marked reduction in the ratio of decompression sickness to astronauts active at zero gravity outside the spacecraft’s spacecraft to the same value of R on the ground. To investigate this, subjects were decompressed using a chair-shaped stent model under simulated microgravity in the low-pressure cabin. Methods The volunteers rested in chairs for 6 hours, then pre-inhaled for 2 hours after 4 hours. Subjects were either slightly active (25 W) or quiet during pre-inhalation O 2. Then in the low-pressure cabin in the seat of the rest, reduced pressure to 30000 feet (9144m) 3h. Those who were resting in the seat pre-oxygenated subjects, and they themselves were at high altitudes
