In 102 school children aged 7 to 12 yr with diagnosed asthma or wheezing in the past 12 months spirometry was performed three times in 4 to 6 weeks intervals. Maximal expiratory flows at low lung volumes (MEF50 and/or MEF25) were reduced in more than one third of children. The reduction of MEF50 and MEF25 was more frequent, more deep, and more persistent in following tests as compared with FEV1%. Small airways obstruction was observed in almost 90% children with FEV1% slightly above limit value.
在102名7至12岁、过去12个月内被诊断为哮喘或喘息的在校儿童中，在4至6周的间隔内进行了3次肺活量测定。超过三分之一的儿童低肺容积时的最大呼气流量（MEF50和/或MEF25）降低。与FEV1%相比，在后续测试中MEF50和MEF25的降低更频繁、更显著且更持久。在FEV1%略高于限值的近90%儿童中观察到小气道阻塞。
