摘　　要：目的:分析平原地区、西宁地区人群急进玉树地区后血氧饱和度(SaO2)变化。方法:应用便携式氧饱和度检测仪,检测两地区人群进入玉树地区12小时、24小时、72小时、7天的SaO2并进行分析,了解SaO2变化与发生急性高原病(AHAD)的相关性。结果:平原地区人群SaO2为(85.7±1.6)%时易发生AHAD,发生率为25%。西宁地区人群SaO2为(83.7±2.1)%时易发生AHAD,发生率为21%。结论:SaO2检测可作为筛选AHAD的一个生物学指标。平原地区人群急进玉树地区(3 750m)SaO2较海平面下降11%、西宁地区人群SaO2下降13%,可作为预测发生AHAD指标。Objective:To observe changes of blood oxygen saturation(SaO2) in crows acute exposed to high altitude from plain and Xining region.Methods:1 200 volunteer from plain(over sea level 7m) and Xining area(2 260m)were exposed to Yushu(3 750m) quickly,and were assigned at the first group(plain crowd,n=500) and the 2nd group(Xining crowd,n=700).Level of SaO2 was measured after 12h,24h,72h and 7days exposed Yushu by a portable oxygen saturation detector.Acute mountain sickness(AMS)was examined in the both groups in Yushu on the basis of the diagnostic criteria of AMS in Sep.1995.Results:Incidence of AMS began at(83.7±2.1)% of SaO2(a 25% incidence) In the first group,and began at(83.7±2.1)% of SaO2 for the 2nd group(a 21% incidence).Level of SaO2 in plain crowd from plain to Yushu decreased 11%;13% decrease for Xining crowd.Conclusions:Detection of SaO2 and change of SaO2 level could be a biological marker in diagnosis of AMS at high altitude.
