目的 了解海上饱和潜水环境下，机体主要器官功能变化、适应性和工作能力。检验饱和－巡回潜水医学保障方案。方法 ８名潜水员利用国产大深度饱和潜水系统和Ｈｅｌｉｏｘ－１８ｂ 型潜水装具，依据制定的医学保障方案，执行海上大深度饱和－巡回潜水。潜水分三阶段：１． 潜水员选拔训练和物质准备。２． 由浅入深进行空气和氦氧邦司潜水。３． １２０ ｍ ＨｅＯ２ 饱和－１５０ ｍ 巡回潜水实潜。饱和加压速度１ ｍ ／ｍ ｉｎ，每１０ ｍ 增值停留２ 分钟，６０ ｍ 深度停留２０ 分钟。在饱和深度下，主要环境参数：舱压１．３ＭＰａ，ＰＯ２ ４０ ｋＰａ，ＰＣＯ２ ＜ １ｋＰａ，ＰＮ２ ＜ １４０ ｋＰａ，ＰＨｅ １．１２ ＭＰａ。舱温（３０±１） ℃，相对温度５０％ ～７０％ 。巡回潜水时，呼吸７％ Ｏ２－９３％ Ｈｅ混合气。饱和减压每５ ｍ 为一站，随深度减少，停留时间增加。减压时进行心前区Ｄｏｐｐｌｅｒ气泡监测。潜水全过程不同阶段，结合进行了脑电图、心电图、胃电图、肺功能、神经运动性功能、血与尿生化、免疫学等指标测试和临床医学观察。结果 潜水员在１２０ ｍ 氦氧环境下驻留６４ 小时，完成９ 钟次２０ 人次，１４４～１４９ ｍ 深度范围巡回潜水；减压１３１ 小时，压力?
Objective To understand the functional changes, adaptability and working ability of major organs under sea saturated diving environment. Test Saturation - Tour Diving Medical Assurance Program. Methods Eight divers used domestic deep deep saturation diving system and Heliox-18b diving gear to perform deep deep saturation-circuit diving at sea according to the established medical protection scheme. Diving in three phases: 1. Diver selection training and material preparation. 2. From shallow to deep for air and helix dive. 3. 120 m HeO2 saturation -150 m Roving diving potential. Saturation pressure rate 1 m / m in, 2 mins for every 10 m increments, 20 mins for 60 m depths. At saturation depth, the main environmental parameters are: cabin pressure 1.3 MPa, PO2 40 kPa, PCO2 <1 kPa, PN2 <140 kPa, PHe 1.12 MPa. Cabin temperature (30 ± 1) ℃, the relative temperature of 50% to 70%. When diving, breathe 7% O2-93% He mixture. Saturated decompression every 5 m for a station, with the depth reduction, dwell time increases. Decompression before Doppler bubble monitoring. Diving the different stages of the whole process, combined with the EEG, ECG, electrogastrogram, pulmonary function, motor function, blood and urine biochemistry, immunology and other indicators of testing and clinical observation. Results The diver resided for 64 hours in 120 m helium oxygen environment, completing 9 times of 20 person trips and 144-149 m of depth diving tour; decompression of 131 hours, pressure
