The peak expiratory flow (PEF), also called peak expiratory flow rate (PEFR) and peak flow measurement, [1] 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.
Sniff nasal inspiratory pressure (SNIP) refers to short, sharp voluntary inspiratory maneuver (inhalation) through one or both un-occluded (not closed or obstructed) nostrils. The tests are performed at FRC (functional residual capacity), at the end of tidal expiration. The measurement recorded is the peak pressure.
For example, maximum inspiratory flow is denoted FIF max. Unless otherwise specified, volume qualifiers indicate the volume inspired from RV at the point of measurement.) PEF: Peak expiratory flow: The highest forced expiratory flow measured with a peak flow meter: MVV

Peak/mean inspiratory and expiratory flow measures the presence of upper airway flow limitations during inspiration and expiration. %RCi is the percent contribution of the rib cage excursions to the tidal volume Vt. The %RCi contribution to Tidal Volume ratio is obtained by dividing the inspired volume in the RC band by the inspired volume in ...
1959 Wright B. M. and McKerrow C. B. introduced the peak flow meter 1969 DuBois A. B. and van de Woestijne K. P. experimented on humans using the whole body plethysmograph 1974 Campbell et al. refined the previous peak flow meter, developing a cheaper and lighter version [ 2 ]
