摘　　要：对272例健康人进行了肺活量、最大呼气流量—容积曲线测定。以横向年龄分组的方法分析了年龄对通气功能各参数的影响。最大呼气中期流量(MMEF)与50％和25％肺活量时的最大呼气流量及其身高的比值((?)_(50)、(?)_(25)、(?)_(50)/HT、(?)_(25)/HT)高度相。认为MMEF也可作为小气道功能测定的指标。Maximum expiratory flow-volume curve (MEFV) and vital capacity were measured in 272 healthy subjects. We analysed the influence of aging on each parameter of ventilatory function with the method of cross-section study. The result also showed that maximum mid expiratory flow rate (MMEF was highly related to_(50), _(25), _(50)/HT, and _(25)/HT. Hence, MMEF could also be considered as a parameter of small airway function test.
