摘　　要：目的了解高原环境对急进格尔木试验人员血氧血压心率影响的变化规律。方法对急进格尔木试验人员进行血氧血压心率试验观察,对比常住人员分析其变化。对初次进驻高原试验人员在不同海拔高度下以及在格尔木市区(同一海拔高度下)停留期间的血氧血压心率进行连续性观察测量,分析其变化规律。结果急进高原试验人员组与常住试验场人员组之间,血氧饱和度、血压及心率差异均无统计学意义(P>0.05),但两组人员血氧饱和度平均值为(83.50±4.35)%,与正常值(90%)相比,显著降低(P<0.05)。血压达到高血压标准,高原高血压发病率分别为20%和40%;初次急进高原受试人员血氧饱和度、血压与海拔高度存在显著的线性相关关系(P<0.05),随海拔高度的升高血氧饱和度显著降低(r=-0.909),血压明显升高(r=-0.806)。而心率与海拔高度无明显的线性相关性(P>0.05)。血氧饱和度与高原停留时间存在相关性(r=-0.676,P<0.05),而血压、心率与高原停留时间无相关性。结论高原环境下海拔高度与血氧饱和度和血压存在相关性。[Objective]To study the changes of blood oxygen saturation（Sa O2）, blood pressure（ BP）, and heart rate（ HR） of testing personnels after acute exposure to high altitude.[Methods] The levels of Sa O2,BP and HR of testing personnels who were acutely exposure to the high altitude of Golmud,and the changes were analyzed by comparison with the resident testing personnels. The levels of Sa O2,BP and HR of testing personnels stationed in the plateau for the first time at different altitudes and in Golmud urban area（at the same altitude） were observed and measured continuously,to analyze the change rule.[Results]There were no statistically significant differences in levels of Sa O2,BP and HR between acute exposure to high altitude personnels and the resident testing personnels. The average value of Sa O2 in two groups was（83.50±4.35）%,which was lower than the normal value（90%） significantly（P0.05）. The incidence of high altitude hypertension was 20% and 40% respectively. The levels of Sa O2 and BP in testing personnels after acute exposure to high altitudewere significantly linearly correlated with altitude（P0.05）,and the level of Sa O2 significantly decreased（r=-0.909） while the level of BP significantly increased（r=-0.806） with increase of altitude. However,the there was no significant correlation between HR and altitude（P0.05）. There was correlation between Sa O2 and residence time on plateau（correlation coefficient r=-0.676,P0.05）,and the levels of BP and HR were not correlated with residence time.[Conclusion]The levels of Sa O2 and BP are correlated with altitude in plateau environment.
