peak expiratory flow

基本解释

Objective To study the clinical application of the peak expiratory flow rate( PEFR) in children with asthma.
目的探讨最大呼气峰流速（PEFR）在儿童哮喘诊治中的临床应用价值。
In addition, red tide exposure was associated with significant reductions in FEV1, midexpiratory phase of forced expiratory flow, and peak expiratory flow.
另外，暴露于红潮会引起FEV1——强迫呼气流量中值和呼气气流峰值减少。
Compared with the placebo situation, the use of the UV irradiation system was associated with a significant improvement in the children's peak expiratory flow rate, the report indicates.
报道指出，与空白对照相比，紫外辐照系统的使用与（患哮喘）孩子的最大呼气流速的明显改善存在相关性。

But soon after, I developed a novel mathematical model which can be used by doctors and environmental specialists to quantify the effect of the pollutants on the lung function as measured by the peak expiratory flow rate-- which is essentially how much a person can breathe out in one breath.
