中美联合25m氮氧饱和—空气巡潜科学实验

Sino-US Joint Experiment on 25m NITROX Saturation Excursion Diving

中美科技工作者首次在我国联合进行了为期七天的25m氮氧饱和空气巡潜科学实验,在五天饱和停留期间,四名潜水员进行了60人次50～75m不减压与减压反复巡潜。完成了Doppler监测和肺、心,脑生理功能测试,经53h50min减压,潜水员安全出舱,无一例减压病症。本实验方案对当前饱和潜水的新程序、巡潜深度时限、高压氧暴露限度以及饱和减压等进行了有效的探索,并对其安全性、实用性进行了验证。

A 7-day experiment on 25m NITROX saturation excursion diving was jointly conducted for the first time in China by scientists from China and the USA. During the period of a 5days saturation stay, 4 divers made 60 person-times of 50 to 75 m nondecompression-and-decompression repetitive excursion divings. Doppler monitoring was performedand tests on physiological functions of lung, heart and brain wet successfully made. The divers came out of the chamber safely after decompression for 3 hours and 50 minutes and none of them suffered from decompression sickness. In the experiment, studies were made on the new saturation diving, procedures, depth and time limits of saturation diving, limit of exposure to hyperbaric oxygen and saturation decompression, and tests were made on their safety and Practicability.
