本文对青海省果洛州(海拔3730米)8名健康成年人和抵平原(苏州,海拔10米)的青海省天峻县(海拔3500～3700米)的12名健康成年人,分别连续7小时用多导仪临测夜间睡眠变化,进行对比研究。发现总睡眠时间A组较B组有减少趋势;总醒觉时间占实际记录百分比A组较B组明显增多(P<0.05);有效睡眠指数百分比,REM占总睡眠时间百分比A组较B组显著减少(P<0.01);N—REM占总睡眠时间百分比A组较B组明显增多(P<0.05)。慢性高原低氧对人体神经系统的影响主要为机能紊乱和大脑皮层功能失调。这些改变抵平原后随停留时间的延长而具有可变性。
In this paper, eight healthy adults in Guoluo (Qinghai) at an altitude of 3730 meters and 12 healthy adults in Tianjun (Qinghai Province) at an altitude of 3,500 to 3,700 meters above sea level (Suzhou, 10 meters above sea level) Hours with multi-channel instrument to measure changes in nighttime sleep, comparative study. The total sleep time in A group was lower than that in B group. The total arousal time in A group was significantly higher than that in B group (P <0.05). The percentage of effective sleep index, REM percentage of total sleep time in group A was significantly higher than that in group B (P <0.01). The percentage of N-REM in total sleep time in group A was significantly higher than that in group B (P <0.05). The effects of chronic high altitude hypoxia on the human nervous system are mainly dysfunction and cerebral cortex dysfunction. These changes are inherently variable with the extension of stay.
