对于小气道功能的测定主要手段有最大呼气流速——容量曲线(MEFV)、闭合气量及频率依赖的肺应变性测定。国内少数单位已开始应用上述检查方法测定正常值、吸烟或大气污染对其影响的观察及在慢性阻塞性肺疾病时变异特点的分析工作,但对其测定结果的评价,国内报道不尽一致。此文介绍的是其中的一部份:长春地区200例健康成人MEFV
The primary means of determining small airway function is maximum expiratory flow-volume curve (MEFV), closed volume, and frequency-dependent lung strain measurements. A small number of domestic units have begun to use the above test to determine the normal value of the impact of smoking or air pollution and the analysis of the characteristics of the changes in chronic obstructive pulmonary disease analysis, but its evaluation of the results of evaluation, the domestic reports are not consistent. This article describes some of them: Changchun area 200 healthy adults MEFV
