测定了39名男性健康吸烟者的14项小气道功道指标,40名男性健康不吸烟者作对照组。用力呼气有关的6项指标在低年龄组均无显著差异;在中年龄组MTT有显著差异;在高年龄组均有非常显著差异。闭合容积、等流量容积曲线、一氧化碳弥散量在各年龄组均不能区分吸烟与不吸组的差别。吸烟引起的MTT、MET改变随年龄增长而显著增大。结果表明:MTT等用力呼气指标检测早期小气道功能异常的敏感性优于闭合容积、等流量容积曲线、一氧化碳弥散量等方法。
A total of 14 small airway target indicators of 39 male healthy smokers and 40 healthy male non-smokers were selected as controls. Forced expiratory 6 indicators related to low age groups were no significant differences in the MTT in the middle age group were significantly different in the high age group were very significant differences. Closure volume, flow volume curve, carbon monoxide dispersion in each age group can not distinguish between smoking and smoking group difference. Smoking caused by MTT, MET changes significantly increased with age. The results showed that the sensitivities of MTT and other forced expiratory indexes in detecting early small airway dysfunction were better than that of closed volume, isometric volume curve and carbon monoxide dispersion.
