吸烟可造成慢性支气管炎和阻塞性肺气肿,其发病是一个慢性过程,形成慢性支气管炎、肺气肿前先有小气道受损。有多种肺功能检查方法,但都比较复系。文中采用一口气肺功能仪(日本产HI289型)对石家庄市烟厂、袜厂工人及行政干部共104人进行肺功能测定,其中男63人,女41人;吸烟组58人,被动吸烟组19人,正常对照组27人。吸烟组58人中,一秒率(FEV1.0％)低于正常者21人,占吸烟组的36.2％;最大呼气中期流速(mmEF)<正常者33人,占58.8％;用力肺活量(FVC)下降12人,占22.6％;肺活量(VC)下降6人,占10.3％;最大通气量(MVV)下降12人,占20.7％。被动吸烟组中19人中,FEV1.0％异常者10人,占52.6％;mmEF下
Smoking can cause chronic bronchitis and obstructive pulmonary emphysema, its incidence is a chronic process, the formation of chronic bronchitis, emphysema before a small airway damage. There are a variety of lung function tests, but are more complex. A total of 104 people in Shijiazhuang Tobacco Factory, Hosiery Factory Workers and Administrative Cadres were enrolled in this study, including 63 males and 41 females, and 58 smokers and passive smokers 19, normal control group of 27 people. Among the 58 smokers, the one-second rate (FEV1.0%) was lower than that of the normal subjects (21.2%), accounting for 36.2% of the smokers; the mean maximum expiratory flow rate (mmEF) FVC decreased by 12, accounting for 22.6%; the vital capacity (VC) decreased by 6, accounting for 10.3%; the maximal ventilation (MVV) decreased by 12, accounting for 20.7%. Passive smoking group of 19 people, FEV1.0% abnormal 10 people, accounting for 52.6%; mmEF
