吸烟对健康者肺功能的影响

Effects of smoking on pulmonary function of healthy adults

目的:研究吸烟对人体肺功能的影响,提高人们早期戒烟意识。方法:应用MedGraphics 1085D肺功能仪(美国)对我院体检中心161例健康成年人进行肺功能检测,探讨吸烟对肺功能的影响。结果:吸烟组中FEV1、FVC、FEV1/FVC明显低于对照组(P<0.05);小气道功能指数FEF50%、FEF75%、MMEF显著降低(P<0.01)。结论:健康吸烟者肺通气功能较非吸烟者有不同程度的下降,且以阻塞性通气功能及小气道功能损害为主;肺功能检查对气道疾病早期诊断具有重要意义。

Objective： To observe effects of smoking on pulmonary fuction of health adult,and to urge smokers give up smoking as early as possible. Methods： 161 cases of healthy adults who took physical examination in the medical examination center of our hospital took the pulmonary function testing by MedGraphics 1085D spirometer, and the effects of cigarette smoking on pulmonary function were analyzed. Results： There was a significant difference between nonsmokers and smokers in indexes such as FEV1, FVC, FEV1/FVC（P〈0.05）, the indexes of the small airway function （FEF50%, FEF75%, MMEF） significantly dropped （P〈0.01）. Conclusion： The pulmonary function of health smokers, especially small airway function have already been impaired compared with nonsmokers. For earlier diagnosing of lung diseases, pulmonary function test is significant.
