The difference between oversea predicted values and Chinese healthy adult measurements of spirometry in shenyang / 中国实用内科杂志

ABSTRACT

Objective To evaluate if the difference between oversea predicted values and healthy adult measurements of spirometry in shenyang.Methods 287 healthy adult volunteers underwent pulmonary function test.The measurements of spiromenty of 230 selected objects were compared to conventional oversea predicted values.Results In male group(154 objects),the measured values were as followsVC(4.4?0.7)L,FVC(4.3?0.7)L,FEV1(3.5?0.6)L,FEF25%～75%(3.6?1.1)L/s,PEF(7.1?1.9)L/s,IC(2.8?0.7)L,respectively.In female group(76 objects),the measured values were as followsVC(3.1?0.7)L,FVC(3.1?0.7)L,FEV1 2.5?0.6(L),FEF25%～75%(2.6?0.9)L/s,PEF(5.0?1.4)L/s,IC(2.1?0.7)L respectively.The measurements were 2%～26% and 2%～21% lower than the predicted values in male and female respectively.The major compared values had significant difference.Conclusion The major measured values of spirometry in healthy adult in shenyang were significantly lower than the oversea predicted values.Knudson or ECCS regression equations with appropriate correction factor were suggested to use in shenyang.
