Abstract

In an effort to determine which measure of airway dynamics was the most sensitive to airway obstruction, comparisons were made between a variety of tests. Twenty cigarette smokers were studied both before and immediately after smoking a cigarette. The maximum midexpiratory flow (FEV25-75) and the FEV1/FVC per cent were abnormal in the largest number of cases. Closing volume was abnormal in only one case. Significant worsening in function after smoking a cigarette occurred in airway resistance and specific conductance. A lesser degree of impairment in airway dynamics was evident from FEV25-75 and first-second expired volume. The closing volume showed no change.

摘要

为了确定哪种气道动力学指标对气道阻塞最敏感,对多种测试进行了比较。对20名吸烟者在吸烟前和吸烟后立即进行了研究。最大呼气中期流速(FEV25 - 75)和FEV1/FVC百分比在大多数病例中异常。闭合气量仅在1例中异常。吸烟后气道阻力和比传导率的功能显著恶化。从FEV25 - 75和第一秒与第二秒呼出量可明显看出气道动力学有较轻程度的损害。闭合气量无变化。
