Lung compliance (CL) and maximal expiratory flow-volume curves (MEFV) breathing air and helium-oxygen mixture in 34 healthy nonsmokers and 55 young light smokers were studied. The difference of FEV1%, PEFR and MMEF between smokers and nonsmokers were statistically significant. The results of small airway function tests were compared and analysed. In the 55 smokers, 38(69.1%) showed frequency dependence of dynamic compliance (FDC), only 5(9.1%) had an abnormal V25/HT and 4(7.3%) showed an abnormal MMEF. of 48 smokers (31.3%) had an abnormal volume of isoflow (VisoV), We concluded that among the small airway function tests FDC is the most sensitive one in light smokers.
对34名健康不吸烟者和55名年轻轻度吸烟者吸入空气和氦氧混合气时的肺顺应性（CL）和最大呼气流量-容积曲线（MEFV）进行了研究。吸烟者与不吸烟者之间的第1秒用力呼气容积百分比（FEV1%）、呼气峰流速（PEFR）和最大呼气中期流速（MMEF）差异具有统计学意义。对小气道功能测试结果进行了比较和分析。在55名吸烟者中，38名（69.1%）表现出动态顺应性频率依赖性（FDC），只有5名（9.1%）的V25/HT异常，4名（7.3%）的MMEF异常。48名吸烟者（31.3%）等流量容积（VisoV）异常。我们得出结论，在小气道功能测试中，FDC对轻度吸烟者最敏感。
