肺功能测定对急性高原反应易感者预测价值的初步探讨

目的：探讨肺功能测定对急性高原反应(AMS)易感者的预测作用。方法：随机选择内地籍人藏新兵113人，进藏前(海拔300m)进行肺功能检测，然后空运进入高原地区(海拔3658m)；人藏后第2天和第3天进行急性高原反应症状学评分。将两组数据进行相关分析。结果：急性高原反应者的用力肺活量(FVC)、最大呼气流量(PEF)和18用力呼气容积(FEV1．0)显著低于无反应者，AMS与受试者FVC、FEV1、PEF等指标显著相关。结论：平原肺功能测定有益于AMS易感者的筛选。

Predictive effect of lung functional determination of the population susceptible to acute mountain sickness

Objective: Probing into the correlativit y of lung functional index and grade of acute mountain sickness (AMS) to establish the predictive index of susceptible population to AMS. Methods: Randomly choosed 113 male recruits from their native places in plain to Tibet by air-transportation. Their lung function was determined at the altitude of 300 m before air-transportation. Semeiology grade of AMS was done 2 or 3 days after their arrival at the altitude of 3 658 m, and correlative analysis of each lung functional index and semeiology grade of AMS was subsequently conducted. Results: Th e forced expiratory volume in one second (PEV1.0) and peak expiratory flow (PEF) and forced vital capacity(FVC) of susceptible population to AMS were obviously smaller than that of non-susceptible population, therefore remarkably correlated with AMS. Conclusion: Lung functional determination in plain plays a role on prediction of the people susceptible to AMS.
