In this study the maximal mid-expiratory flow (MMEF) was compared with forced expiratory volume in 1 sec (FEV1) by a spirometric investigation of healthy children and children with slight bronchial obstruction. We found that the reproducibility of MMEF was good in both healthy and asthmatic children and that both methods had the same ability to detect abnormality before inhalation of a beta 2-receptor agonist. After such an inhalation the discriminatory power was greater for FEV1 than for MMEF and we therefore prefer FEV1 in estimating bronchial obstruction in children.
在本研究中，通过对健康儿童和轻度支气管阻塞儿童进行肺量计检查，比较了最大呼气中期流量（MMEF）与第1秒用力呼气量（FEV1）。我们发现，MMEF在健康儿童和哮喘儿童中的可重复性都很好，并且在吸入β2受体激动剂之前，两种方法检测异常的能力相同。吸入后，FEV1的鉴别能力比MMEF更强，因此我们在评估儿童支气管阻塞时更倾向于使用FEV1。
