目的:调查与分析玉树地震灾区(平均海拔3 750m)重建人员在高原环境下血氧饱和度、血压、心率等的变化。方法:运用便携式氧饱和度检测仪及血压计,检测148名健康重建人群的血氧饱和度(SaO2)、血压(Bp)及心率(HR),并按年龄分布和劳动强度分布,比较两因素对人体的SaO2、Bp及HR的影响。结果:玉树地区进驻人员的平均SaO2、平均Bp及心率HR分别为:89.0%±1.2%、(131.7±3.1)mmHg/(85.5±1.6)mmHg、(84.3±2.5)min-1。劳动强度三组间SaO2无差别,HR、Bp有显著性差别。年龄段三组间平均SaO2、平均HR,平均Bp均有显著性差别。Logistic回归分析提示年龄因素和劳动强度影响人体对高原的适应。结论:玉树地区援建人员的SaO2、Bp及HR随年龄增大出现异常,劳动强度增加心肺功能的负担。
Objective: To investigate and analyze the changes of oxygen saturation, blood pressure, heart rate and so on under the plateau environment in the Yushu earthquake-stricken area (with an average altitude of 3 750m). Methods: The blood oxygen saturation (SaO2), blood pressure (Bp) and heart rate (HR) of 148 healthy people were detected by portable oxygen saturation detector and sphygmomanometer. The distribution of age and labor intensity were compared between two factors Impact on human body SaO2, Bp and HR. Results: The mean SaO2, mean Bp and HR of recruits in Yushu were 89.0% ± 1.2%, 131.7 ± 3.1 mmHg / (85.5 ± 1.6) mmHg and (84.3 ± 2.5) min-1, respectively. Labor intensity SaO2 no difference between the three groups, HR, Bp significant difference. The average SaO2, average HR, average Bp among the three age groups were significantly different. Logistic regression analysis suggested that age and labor intensity affect the body’s adaptation to the plateau. Conclusion: The SaO2, Bp and HR of aided workers in Yushu area appear abnormal with age, and labor intensity increases the burden of cardiopulmonary function.
