我国在海拔4000～5000米高原有着丰富的水力资源,高原地区的水利建设中,水下作业是必不可少的技术手段。国內外很少研究此特殊环境潜水生理、医学问题。从1971年开始,瑞士苏黎世大学医院的A A Buehmann等进行了106次模拟海拨3000米的舱内潜水,其中海拔1510～2000米潜水深度30米、海拔2001～2500米潜水深度20米、2501～3200米潜水深度18米。1974、1975年我国海军医学研究所、上海救捞局、上海生理研究所等单位,先后在海拨1700米进行了水深146～156米的人体氦氧深潜水实验。但海拔4500～5000米潜水深
China has abundant water resources at an altitude of 4,000 to 5,000 meters above sea level. During the water conservancy construction in the plateau, underwater operation is an indispensable technical measure. Few domestic and foreign researches on physiological and medical problems of diving in this special environment. From 1971, AA Buehmann, University Hospital Zurich, Switzerland conducted 106 in-flight simulations of 3000 meters above sea level, of which 1510 to 2000 meters above sea level and 30 meters above sea level, diving depths of 20 meters to 200 meters and 2001 to 2500 meters, 3200 meters diving depth of 18 meters. In 1974 and 1975, the Chinese Academy of Naval Medical Research, Shanghai Rescue and Salvage Bureau, Shanghai Institute of Physiology and other units successively carried out deep-sea helium-oxygen diving tests at depths of 146-156 meters at an altitude of 1,700 meters. But diving 4500 ~ 5000 meters above sea level deep
