摘要
２１２例老年男性分为健康组、慢支并肺气肿组、肺心病组观察其最大呼气流速一容量曲线（ＭＥＦＶ曲线）中的５个指标ＭＭＥＦ，Ｖ＿（０．７５），Ｖ＿（１．５０），Ｖ＿（０．２５）和Ｖ＿（０．５０）／Ｖ＿（０．２５）的变化并进行组间对此研究。结果发现健康组与慢支并肺气肿组比较，除Ｖ＿（０．５０）／Ｖ＿（０．２５）外，其余４项指标均有极显著性差异（Ｐ＜０．０１）；肺心病组与慢支并肺气肿组比较均有极显著性差异（Ｐ＜０．０１），而且随病程的延长和病情的加重，数值逐级减少，结果提示，此４项指标可作为反映早期小气道功能改变敏感的指标，男性健康老年人在６０岁以后，小气道功能改变很小。
Reported here were five MMEF parameters,e.g.V_(0.75),V_(0.50),V_(0.25) andV_(0.5)/V_(0.25),of maximal expiratory flow-volume curve(MEFV)in 212 old males,The patientswere divided into normal group,chronic bronchitis and emphysema group,and cor pulmonalegroup,with a contrast study made among them.The result showed that an obvious difference(P<0.01)was observed in other four parameters except in V_(0.5)/V_(0.25) ,and the numerical valuedecreased gradually with disease course extending and worsening.Thus the four parameterscould be identified as sensitive indexes for the reflection of small airway function alteration at theearly stage.The healthy old men’s small airway function changed a little after the age of sixty.
