摘要
[目的]探讨吸烟对人体肺功能的影响,提高尽早戒烟的意识。[方法]采用MedGraphics 1085D肺功能仪(美国)对大连医科大学附属第二医院健康体检中151名健康成年人进行肺功能检测,分析吸烟对肺功能的影响。[结果]在肺功能检测指标中,吸烟组(81例)与不吸烟组(70例)相比,吸烟组肺活量(VC)、1秒率(FEV1/FVC)、最大分钟通气量(MVV)、FEF50%、FEF75%、MMEF均较非吸烟组明显降低(P均<0.05);吸烟组与非吸烟组FVC、FEV1、FEV1/VC差异无显著性意义。[结论]无临床症状吸烟者与非吸烟者相比,肺活量、通气功能、小气道功能明显降低;肺功能检查对无临床症状吸烟者具有重要意义。
[ Objective] This study is to investigate the effects of cigarette smoking on lung function and to urge smokers to give up smoking as early as possible. [ Methods] One hundred fifty- one healthy adults, who took physical examination at the Second Affiliated Hospital of Dalian Medical University, took the pulmonary function testing by MedGraphics 1085D spirometer. And the effects of cigarette smoking on lung function were analyzed. [ Results ] No significant difference （P 〉 0.05 ） was found between nonsmokers and smokers in two indexes, FVC （forced vital capacity） and FEV1 （forced expiratory volume in 1 second）. But there was significant difference between nonsmokers and smokers in indexes such as lung capacity -VC （vital capacity） , FEVI/VC and some pulmonary ventilatory function indicants, MVV （maximal voluntary ventilation） and FEV1/FVC （P 〈 0.05）. The indexes of the small airway function （FEF50% , FEF75%, MMEF） had significantly dropped （P 〈0.01 ）. [ Conclusion] Although smokers have not shown clinical symptoms, their lung functions, especially small airway function had already been impaired, compared to nonsmokers. Pulmonary function test was significant for asymptomatie smokers.
