通气功能测定是肺功能检查中最常用的功能测定。鉴于地区不同肺功能有所差异,本文对南通地区413名人员作常规肺通气功能检查,然后作出正常估计值的回归方程;并就吸烟对小气道的影响也作了初步分析。资料和方法一、对象选择受检者中146名为无心肺疾患、无慢性咳喘的不吸烟健康人(机关干部和学生,其中20～29岁60人,30～39岁28人,40～49岁28人,50～59岁29人)。另选66名无症状的男性吸烟者(教师,其中30～39岁13人,40～49岁29人,50～59岁21人,60～69岁3人)。为了讨论本测定的临床意义,还对98名慢性阻塞性肺病(简称慢阻肺)患者和103名其他肺部疾病
Ventilation function testing is the most commonly used function test in pulmonary function tests. In view of the differences in lung function in different regions, we conducted a routine pulmonary function test on 413 people in Nantong area and then made regression equations of normal estimates. The effects of smoking on small airways were also analyzed. Materials and Methods 1. Subjects 146 non-smokers (cadres and students aged 60-29 years, 28, 30-39 years old, non-smokers, non-smokers, non-smokers, 49 years old 28 people, 50 to 59 years old 29 people). Another 66 asymptomatic male smokers (teachers, 13 of them 30 to 39, 29 of 40 to 49, 21 of 50 to 59, and 3 of 60 to 69) were enrolled. In order to discuss the clinical significance of this assay, 98 chronic obstructive pulmonary disease (COPD) patients and 103 other pulmonary diseases
