呼气相

其他转归包括支气管扩张剂治疗前后的一秒钟用力呼气容积(FEV1)、急性加重频率、哮喘控制程度、无症状天数和生活质量。

主要转归是早晨峰呼气流速(PEF)。

研究者用用力第一秒呼气量(FEV1)和用力肺活量(FVC)和其预期值的百分比(FVCPP)作为肺功能衡量指标。

FVE(forced expiratory volume)

peak expiratory flow, PEF

percentage of forced expiratory volume in first second to forced vital capacity, FEV1%

PEF(peak expiratory flow)

forced expiratory volume in first second, FEV1

expiratory flow during middle half of the FVC

expiratory port occlusion

end-expiratory esophageal pressure
