摘要
目的探讨FET25%￣75%正常值及在COPD临床应用。方法对222例健康成人和86例健康吸烟者及196例COPD患者进行了FET25%￣75%测定。结果健康人FET25%￣75%与年龄密切相关(P<0.01),计算出其预计回归方程式,COPD和健康吸烟组与健康成人进行比较,FET25%￣75%明显延长(P<0.01)。结论FET25%￣75%测定是一项相对独立于容量的阻塞性功能判定指标。
[Objective] To study FET25%-75% normal value and its clinical value in COPD. [Methods] The FET 25%-75% of 222 healthy adult,86 healthy adult smokers and 196 cases of COPD were detected. [Results] The FET25%-75% of healthy adult is significandy correlation with age （P 〈0.01）. The regression equation showes that the FET25%-75% of COPD and healthy adult smokers is signifieandy prolonged compared with that of healthy adult （P 〈0.01）. [Conclusion] The detection of FET25%-75% is a relatively independent index in the evaluation of obstructive funtion.
