目的 :了解快速进入高原者机体在高原低氧环境下肺功能改变及其意义。方法 :在 15 0名快速进入高原者中随机抽取 4 0人 ,于进藏前 1d及进藏的第 3d和第 7d分别进行肺功能检测 ,检测项目包括用力肺活量 (FVC)、一秒通气量 (FEV1.0 )、用力肺活量 /肺活量预测值 (%FVC)、一秒率(FEV1.0 % )、最大峰流速 (PF)及中期流速 (V75～V2 5 ) ,并对上述指标进行比较。结果 :快速进入高原者进入高原后肺功能各指标检测均较平原值升高 ,其中进入高原第 3d各指标变化尤为显著 ,第7d次之 (P <0 .0 5～ 0 .0 1)。结论 :快速进入高原者为适应高原缺氧环境 ,肺功能会发生由代偿到逐步习服的生理性改变 ,了解此过程 ,对于快速进入高原者AHAD的预防 ,尤其是对快速进驻高原部队合理科学的训练提供了依据。
OBJECTIVE: To understand the significance of pulmonary function changes in fasting plateau patients under plateau hypoxia. Methods: Forty randomly selected 40 individuals from rapid access to the plateau were enrolled in the study. Lung function tests were performed on the first day before entering Tibet and the third and seventh day after entering Tibet. The test items included forced vital capacity (FVC), one second ventilation (FEV1.0), forced vital capacity / predicted vital capacity (% FVC), one second rate (FEV1.0%), maximum peak flow rate (PF) and mid-term flow rate (V75 ~ V25) Results: After entering the plateau rapidly, the indexes of lung function were all higher than those of the plain. The indexes of the third day after entering the plateau were especially significant (P <0.05-0.01). CONCLUSIONS: In order to adapt to the plateau hypoxia environment, rapid lung function changes from compensation to gradual acclimation of physiological changes, to understand this process, the rapid access to high altitude AHAD prevention, especially for rapid stationed in plateau troops reasonable Scientific training provided the basis.
