Materials and Methods: The FVC and FEV values were first measured using a Micro Quark spirometer and then calculated from equations for the European Respiratory Society-93 (ERS-93) in 148 subjects, including 46 girls. In each age group, the measured values for the height of the subjects were considered the only variables used to calculate the equations for FVC and FEV with their 95% confidence intervals. The means of the FEV and FVC values were obtained by univariate analysis. Results: The calculated FEV and FVC values were significantly higher (p Conclusion: The correction factors incorporated in spirometers imported from Europe no longer seem appropriate to measure the physical characteristics of African subjects. The differences between the two methods of assessment should be used as new ethnic correction factors.展开更多
目的探索上海市正常人群第1秒用力吸气容积（forced inspiratory volume in one second，FIV1）的预计值和医学参考值范围。方法对上海地区521名健康成年人，采用德国耶格公司生产的MasterScreendiffusion（SN：694855）型肺功能仪测定F...目的探索上海市正常人群第1秒用力吸气容积（forced inspiratory volume in one second，FIV1）的预计值和医学参考值范围。方法对上海地区521名健康成年人，采用德国耶格公司生产的MasterScreendiffusion（SN：694855）型肺功能仪测定FIV1，探索正常人群FIV。的预计值和医学参考值范围，分析正常人群FIV1与年龄、体质量以及身高的相关性。结果肺功能参数FIV。与身高和年龄呈正相关，但FIV，与身高的关系最为密切，与体质量无关。正常成年男性FIV1预计值的回归方程为FIV1=-5．3510．061＊身高-0．027＊年龄（身高、年龄P〈0．001，体质量P〉0．05），医学参考值范围为2．1075～4．959l；正常成年女性FIV1预计值的回归方程为FIV1=-2．457＋0．04＊身高-0．025＊年龄（身高、年龄P〈0．001，体质量P〉0．05），医学参考值范围为1．2783～3．5171。结论FIV1值与身高和年龄有关，建立并推荐上海地区使用本成人FIV1正常预计值。展开更多
