Variations in the flow/volume curve have been examined in normal subjects in relation to age. It was noted that although flow varies in absolute terms, its fall is constant in both men and women, at equal age. On the other hand, a flow reduction first of 25% and then 50% of CVF was noted in relation to age.
已经在正常受试者中研究了流量/容积曲线随年龄的变化。值得注意的是，尽管流量的绝对值有所变化，但在相同年龄的男性和女性中，其下降是恒定的。另一方面，相对于年龄，观察到流量首先减少25%，然后减少肺活量的50%。
