peak expiratory flow

基本解释

Objective To study the clinical application of the peak expiratory flow rate( PEFR) in children with asthma.
目的探討最大呼氣峰流速（PEFR）在兒童哮喘診治中的臨牀應用價值。
In addition, red tide exposure was associated with significant reductions in FEV1, midexpiratory phase of forced expiratory flow, and peak expiratory flow.
另外，暴露於紅潮會引起FEV1——強迫呼氣流量中值和呼氣氣流峰值減少。
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.
報道指出，與空白對照相比，紫外輻照系統的使用與（患哮喘）孩子的最大呼氣流速的明顯改善存在相關性。

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.
