A new lung function index, the area under the maximum expiratory flow-volume curve (AFVx) is described. A predicted AFVx based on age, sex and height is determined, and the measured to predicted AFVx ratio is assessed by comparison with other established lung function parameters. This ratio appears to be a very sensitive indicator of the degree of lung function impariment.
本文描述了一种新的肺功能指标，即最大呼气流量-容积曲线下面积（AFVx）。基于年龄、性别和身高确定预测的AFVx，并通过与其他已确立的肺功能参数进行比较来评估实测AFVx与预测AFVx的比值。该比值似乎是肺功能损害程度的一个非常敏感的指标。
