呼气峰流速(peak expiratory flow)
呼气峰流速(PEF)及最大呼气流量-容积曲线(MEFV)也可作为气流受限的参考指标 ．胸部X线检查：X线检查对确定肺部并发症 …
最大呼气流量
(2)支气管激发试验阳性或最大呼气流量(PEF)昼夜变异率>20%。(3)支气管扩张剂、糖皮质激素治疗有效。
峰流速(peak flow)
峰流速仪测定峰流速(PEF)就是在胸部充满气体以后用力呼气时，气体流过气道的最快速率。PEF与FEV1高度相关。
最大呼气流速
⑥最大呼气流速(PEF)或第1秒用力呼气量(FEVl)>80％预计值，PEF变异率(PEFR)<20％。 2．治疗目的 无症状者，主要是预 …
呼气流量峰值
或呼气流量峰值（PEF）<80％iE为参考值，吸入受体激动剂后FEV鉴别诊断： 1、喘息型慢性支气管炎：以咳嗽、咳痰为主， …
