对象与方法我院于1991年在体检人群及居民、职工中,根据病史、体检、胸透或胸部摄片以及心电图检查,排除心肺疾患和其它重要脏器病变,选择健康老人163例,其中男112例,女51例。对肺活量、最大通气量、第1、2、3秒用力肺活量和最大呼气中期流速四项,采用日本产 Vitalograph 肺功能机进行检测。测定结果按当时室温和气压换算成37℃水蒸汽饱和的肺内气量。结果与讨论统计结果表明,肺活量、最大通气量和最大呼气中期流速三项指标,男性明显高于女性(P<0.01),肺功能测定平均值随着年龄的增大而降低。第1秒用力肺活量指标,女性明显高于男性(P<0.01),与年龄无明显相关。表1为肺功能测定结果。正常老年人呼吸的储备功能较大,且受年龄、性别、身高、体
Subjects and Methods In 1991, our hospital excluded 163 cases of cardiopulmonary diseases and other important organ diseases from the medical examination population, residents and employees based on medical history, physical examination, chest radiography or chest radiography and electrocardiogram examination. Among them, 163 112 cases, female 51 cases. Vital capacity, the maximum ventilation, the first 1,2,3 second forced vital capacity and maximum expiratory mid-flow rate of four, the Japanese-made Vitalograph lung function testing machine. Measurement results at room temperature and pressure then converted into 37 ℃ water vapor saturated lung volume. Results and Discussion Statistical results show that the three indicators of vital capacity, maximum ventilation and maximum expiratory flow rate are significantly higher in males than in females (P <0.01). The mean value of pulmonary function tests decreases with age. The first second forced vital capacity index, women were significantly higher than men (P <0.01), with no significant correlation with age. Table 1 for the lung function test results. Normal elderly respiratory reserve function larger, and by age, gender, height, body
