peak expiratory flow

最大呼气流量

最大呼气流量(peak expiratory flow，PEF) 是指用力肺活量测定过程中，呼气流速最快时的瞬间流速，亦称峰值呼气流速，主要反映呼吸肌的力量及气道有无阻塞。

abstract: The peak expiratory flow (PEF), also called peak expiratory flow rate (PEFR) is a person's maximum speed of expiration, as measured with a peak flow meter, a small, hand-held device used to monitor a person's ability to breathe out air. It measures the airflow through the bronchi and thus the degree of obstruction in the airways.
