最大呼气流速——容量曲线(MEFV),最大呼气中段流速(MMEF),是检测早期小气道功能较敏感的方法之一.我科于1983～1985年对我国南北方飞行人员进行了测定比较,现报告如下.一、对象和方法(一)对象被检者为21～40岁男性飞行人员.南北方各302例.歼击机173例,运输轰炸机332例,初教机99例,平均飞行时间1129小时(250～3200).健康组:270例,即无心肺病史,体检及胸 The maximum expiratory flow-volume curve (MEFV) and maximum expiratory flow velocity (MMEF) were one of the most sensitive ways to detect the early airway function.Our laboratory measured the flight crew from south to north in China from 1983 to 1985 Comparison, the report is as follows: I. Objects and methods (1) The subjects were 21 to 40-year-old male pilots, 302 cases in the north and south, 173 cases of fighter, 332 cases of transport bomber, 99 cases of primary education, average flight Time 1129 hours (250 ~ 3200) Health group: 270 cases, that is, no history of heart and lung disease, physical examination and chest
