摘要

我们测量了167名20 - 89岁的男女正常人的流量-体积曲线(FV)。所有人都不吸烟,没有人患有心肺疾病。在25%、50%和75%的肺活量(VC)以及肺活量或总肺活量(TLC)归一化的流量通常与年龄有良好的相关系数。参数V25/TLC,尤其是V50/TLC给出了与年龄的最佳相关性,我们建议将来使用这些参数来评估呼吸病理生理。在20 ~ 89岁年龄组中,提出了这些参数随年龄的正态值和回归方程。

[New elements in the interpretation of flow-volume curves].

We have measured flow-volume curves (FV) in 167 normal individuals of both sexes aged 20 to 89. All were non-smokers and none had cardio-respiratory disease. The flows at 25, 50 and 75 per cent of vital capacity (VC) as well as flows normalized by VC or total lung capacity (TLC) gave, in general, good correlation coefficients with age. The parameters V25/TLC and especially V50/TLC gave for the best correlations with age and we suggest these parameters in future when flow volume curves are used to assess respiratory pathophysiology. Normal values as well as regression equations of these parameters with age are proposed for various age groups in the 20-89 years age range.
