许多研究表明长期吸烟会损害肺功能,吸烟者最早期的肺功能改变为小气道功能障碍,闭合气量的测定是发现此种障碍的较常用的方法。有资料表明戒烟或减少每日吸烟量(支数)可改善某些反映小气道功能障碍的肺功能指标。本文报告吸烟后对用力呼气曲线及闭合
Many studies have shown that long-term smoking impairs lung function. The earliest changes in lung function in smokers are small airway dysfunction. Closed air volume measurement is the more commonly used method for detecting this disorder. Data suggest that quitting smoking or reducing the amount of cigarettes smoked per day (burst) may improve some of the lung function indicators that reflect small airway dysfunction. This article reports the forced expiratory curve and closure after smoking
