Abstract

The ventilatory capacity, including flow-volume curves of 313 men, all 50 years old, was examined in 1963 and 1967. The group as a whole, which included persons with chronic bronchitis, with "other respiratory symptoms," and without respiratory symptoms, showed the same absolute decrease in ventilatory capacity.Vital capacity, forced expiratory volume, and maximum expiratory flow all dropped more for the smokers than for either the non-smokers or the ex-smokers. In those who had stopped smoking for four years or less, however, ventilatory capacity did not decline significantly less than in those who continued to smoke.

摘要

1963年和1967年对313名均为50岁男性的通气能力(包括流量-容积曲线)进行了检查。整个群体包括患有慢性支气管炎、有“其他呼吸道症状”以及无呼吸道症状的人,其通气能力出现了相同程度的绝对下降。肺活量、用力呼气量和最大呼气流量在吸烟者中的下降幅度均大于非吸烟者或已戒烟者。然而,在那些戒烟时间为四年或更短的人中,通气能力的下降幅度并不比继续吸烟者明显更小。
