本文对5名吸烟者和5名非吸烟者肺的力学特性进行了测量,在停止吸烟前和停止吸烟后3个月,对每个吸烟者作了详细的肺功能检查,结果如下: 1)吸烟者的呼吸活动倾向小于非吸烟者; 2)吸烟者的肺阻力超过非吸烟者; 3)吸烟者的压力-容量曲线向左偏移较之非吸烟者尤著; 4)停止吸烟后能明显改善某些肺力学特 In this paper, the mechanical properties of the lungs of five smokers and five nonsmokers were measured. Detailed lung function tests were performed on each smoker before stopping smoking and three months after stopping smoking. The results are as follows: 1) Smokers’ respiratory activity tendency is lower than that of non-smokers; 2) Smokers’ lung resistance exceeds that of non-smokers; 3) Smokers’ pressure-volume curve shifts to the left compared with non-smokers; 4) After stopping smoking Significant improvement in certain pulmonary mechanics
