Comparison of circadian variations using FEV1 and peak expiratory flow rates among normal and asthmatic subjects.
BACKGROUND--Most studies that describe circadian variations in asthma have used maximum rate of peak expiratory flow (PEF) rather than forced expiratory volume in one second (FEV1) to assess airway calibre. This study was designed to assess circadian variations in PEF and FEV1 measured simultaneousl...
