模拟36.5米氮氧饱和潜水26昼夜人的生理功能变化和安全减压问题

饱和潜水技术可大大延长水下作业时间、提高潜水作业效率,是开发海底资源、水下施工、援潜救生、海洋考察和科学研究不可缺少的一种手段.近20年来,取得了较大的进展,人体氦氧饱和潜水模拟实验的深度已达650米,现场饱和潜水为460米,巡潜已达501米.     

PHYSIOLOGICAL FUNCTION AND DECOMMISSION DURING LONG-TERM N2-O2 SATURATION DIVING

The present study aims; at (1) examining the effect of prolonged exposure to high pressure on physiological functions: (2) observing performance capacity and adaptive process of the organism, and (3) evaluating the validity of saturation decompression. The results obtained from 7 subjects show that they had good adaptive capacity and could undertake moderate work load. The uniform saturation decompression scheme used and no-decompression ait excursion depth-lime limit were proved to be safe. Up to now, only a few experiments of long-term exposure to 4.65 ATA nitrox atmosphere have been reported throughout the world, so the data accumulated have Jtt reference valuc.
