摘　　要：为研究30min吸氧排氮对模拟出舱活动减压病发生率的影响，通过高空减压病易感性选拔了17名健康成年男性，在低压舱3km高度条件下吸氧排氮30min后，在7．2km高度上模拟出舱活动，观察记录受试者心前区回心血流减压气泡和减压病发生率。发现除高空暴露期间检测到1～2级心前区回心血流气泡信号外，未发生减压病。证实了在3km低压条件下30min吸氧排氮能有效预防模拟出舱活动减压病发生。To study the influence pre-oxygenation on the incidence of decompression sickness during simulated extravehicular activity( EVA),17 health volunteers who passed the susceptibility test of decompression sickness carried out the simulated EVA after 30 min pre-oxygenation in the altitude chamber. The volunteers were monitored for the primordial venous bubble of decompression and the symptoms of decompression sickness. The decompression sickness was not found except the detection of one to two grade bubble signals during the high altitude exposure. The 30 min pre-oxygenation at the 3000 meter altitude exposure can effectively prevent the happening of the decompression sickness incidence during simulated EVA.
