目的 :探讨肺功能与急性高原反应 (AMS)症状学评分之间的相关关系 ,寻找急性高原反应易感者的预测指标。方法 :随机选择内地籍入藏新兵 113人 ,进藏前 (海拔 30 0m)进行肺功能各指标检测 ,然后空运进入高原地区 (海拔 36 5 8m) ;入藏后第二天和第三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 :急性高原反应者的最大呼气流量 (PEF)和 1秒用力呼气容积 (FEV1 0 )明显低于基本无反应者 ,AMS与受试者FVC、FEV1 0和PEF等指标明显相关。表明平原肺功能越好 ,AMS发病的可能性就越小。结论 :平原肺功能测定在一定程度上可对AMS者作出预测 ,有益于AMS易感者的筛选。
Objective: To investigate the relationship between lung function and acute altitude sickness (AMS) symptom score and to find out the predictive value of susceptibility to acute altitude sickness. Methods: 113 native recruits recruited from Tibet were randomly selected for lung function test before they entered Tibet (30 000 m above sea level) and then transported by air into the plateau (elevation of 36 5 8 m). The second day and the third day Acute altitude sickness symptom score, the two groups of data correlation analysis. Results: The peak expiratory flow (PEF) and forced expiratory volume (FEV1 0) in one day were significantly lower than those in non-responders. AMS was significantly correlated with FVC, FEV10 and PEF. That plain lung function is better, the less likely the AMS disease. Conclusion: Plain pulmonary function test can predict AMS patients to a certain extent, which is beneficial to the screening of susceptible AMS patients.
