Methods 110 smokers did the pulmonary testing with 110 nonsmokers by portable spirometers. Results No significant difference was found between nonsmokers and smokers in these indexes such as VT,BF,ERV,IC and VC.To the smoking group,Supported by the Ministry of Science and Technology of China(2001DA30031),the indicants such as FEV1,MVV,FEV1/FVC had decreased (P0.05),and the indexes of the small airway function(PEF、FEF 25、FEF 50、FEF 75、MMEF)had significantly dropped (P0.01).And the smokers especially long-term smokers,most indexes of the pulmonary ventilatory functions and all indexes of the small airway function negatively correlated with smoking indexes. Conclusion Although smokers did not show clinical symptoms,their lung functions had been reduced,especially small airway function.Read More
