Objective The purpose of the study was to explore the influence of lung function and increase lung function. Method 147 patients were selected and recorded their sex、age、smoke status、height、weight、IBM and determinated forced expiratory volume in one sec-ond、forced vital capacity and maximal ventilatory volume et. Results FVC and FEV1 of male were higher than that of female( P﹤0. 05 ) . Lung ventilation function and age was negative correlation( P ﹤0. 05 ). Lung function and height was positively associated( P ﹤0. 05 ) . They were divided into 3 groups according to body mass index(BMI<20、25>BMI≥20、BMI≥25),there was not statistically signifi-cant difference in 3 groups of pulmonary ventilation function( P >0. 05 ). But lung function of normal BMI group was highest in the 3 groups. IN smoking group and no Smoking group there was not statistically significant difference in FVC and FEV1( P >0. 05 ). But no Smoking group was higher. Conclusion Giving up smoking can improve pulmonary ventilation function. Giving nutrition support in patients with weight loss and reducing weight in obese patients can improve pulmonary ventilation function.%目的：探讨肺通气功能的影响因素以提高患者肺通气功能。方法：选择147例患者，记录其性别、年龄、是否吸烟、身高、体重、体重指数，测定第一秒肺呼吸量（ FEV1）、用力肺活量（ FVC）、最大分钟通气量（ MVV）等。结果：男性较女性FVC、FEV1高（P﹤0.05），肺通气功能与年龄呈负相关（P﹤0.05），与身高呈正相关（P﹤0.05），按体重指数（BMI）<20、20≤BMI﹤25、BMI≥25分3组，肺通气功能三组间差异无统计学意义（ P>0.05），但标准体重指数组肺通气功能较佳。FVC实测值、FEV1实测值在吸烟组与非吸烟组比较，差异无统计学意义（ P>0.05），但非吸烟组FVC实测值及FEV1实测值较吸烟组高。结论：戒烟可改善患者肺通气功能，予消瘦患者营养支持、肥胖患者减肥可改善患者肺功能。
