研究戒烟 10年以上老年慢性阻塞性肺疾病(COPD)患者肺功能变化。严格挑选 4 5例戒烟 10年以上老年COPD患者作为研究对象 ,11例从不吸烟老年COPD患者作为对照 ,肺功能检查按常规方法进行。戒烟 10年以上老年COPD患者肺活量 (VC)、用力肺活量(FVC)、一秒钟用力呼气容积 (FEV1)、呼气峰流速 (PEF)、最大呼气中期流量 (MMEF)、最大通气量 (MVV)的 10年后测量值与初始测量值相比P <0 0 1;功能残气量 (FRC)、残气量 /肺总量 (RV/TLC)的 10年后测量值与初始测量值相比P <0 0 5 ;残气量 (RV)及肺总量(TLC)改变无统计学意义。不吸烟老年COPD患者除VC的 10年后测量值与初始值相比P <0 0 5外 ,其他各指标均无统计学意义。戒烟 10年以上老年COPD患者与从不吸烟老年COPD患者肺功能年改变百分比FVCP <0 0 5 ,FRCP <0 0 1。说明戒烟 10年以上老年COPD患者肺功能改变要重于从不吸烟老年COPD患者
To study the changes of lung function in elderly patients with chronic obstructive pulmonary disease (COPD) who quit smoking more than 10 years. Strict selection of 45 cases of smoking cessation of elderly patients with COPD for more than 10 years as a study object, 11 patients with non-smoking elderly COPD patients as a control, pulmonary function tests by conventional methods. Fifty years old COPD patients with smoking cessation of lung volume (VC), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow (PEF), maximum expiratory flow (MMEF), maximum ventilation MVV) after 10 years compared with the original measurement P <0 0 1; after 10 years of measurement of functional residual volume (FRC), residual volume / total lung volume (RV / TLC) compared with the initial measurement P <0 05; There were no significant changes in residual volume (RV) and total lung volume (TLC). Non-smoking elderly COPD patients in addition to VC measured 10 years after the initial value compared with P <0 0 5, the other indicators were not statistically significant. Annual changes in lung function in elderly COPD patients aged more than 10 years with smoking cessation and never smoking elderly patients with COPD were FVCP <0 0 5 and FRCP <0 01. That quit smoking more than 10 years of elderly COPD patients with lung function changes should be heavier than never smoking elderly COPD patients
