| 摘 要： | 对195例健康成人进行的MEFV曲线测定结果表明:PF、(?)_(75)(?)_(50)及(?)_(25),男性较女性高;年龄越大,呼气后段流速越低。慢阻肺患者之呼气后段流速随病情的严重性而降低。在健康人,(?)_(50)/(?)_(25)随年龄的增加而增加,主要表现为(?)_(25)的降低,而109例慢阻肺患者主要表现为(?)_(50)的降低,病情越重,比值越低。MEFV曲线测定方法简便,不需特殊气体,对小气道功能的判定是一个较有价值的检查方法。

| Abstract: | The maximal expiratory flow-volume (MEFV) curve were measured in 195 healthy adults. The results indicated that the values of the peak expiratory flow rate, V_(75), V_(50) and V_(25), were all higher in males than in females, and the higher the age, the lower the end expiratory flow rate. The end expiratory flow rate in chronic obstructive pulmonary disease (COPD) was decreased as the disease deteriorated. In healthy subjects, the V_(50)/V_(35) was increased with age, while in COPD patients V_(50) was decreased. The more severe the condition, the lower the rate. The authors suggest that the measurement of MEFV be used as a simple valuable method to evaluate small air way functiovs. |
