    The maximum instantaneous flow achieved during a FVC maneuver: FIF: Forced inspiratory flow: (Specific measurement of the forced inspiratory curve is denoted by nomenclature analogous to that for the forced expiratory curve. For example, maximum inspiratory flow is denoted FIF max. Unless otherwise specified, volume qualifiers indicate the ...

    MMEF or MEF stands for maximal (mid-)expiratory flow and is the peak of expiratory flow as taken from the flow-volume curve and measured in liters per second. It should theoretically be identical to peak expiratory flow (PEF), which is, however, generally measured by a peak flow meter and given in liters per minute. [16]

    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 ...

    P ip — Peak inspiratory pressure; P plat — Plateau pressure (airway) M paw — Mean airway pressure; E PAP — Pressure applied to exhalation; I PAP — Pressure applied to inhalation; P high — Highest pressure attained, similar to P ip; this is a constant pressure. P low — Pressure that P high drops to during expiratory time (T low)

  8. Respiratory pressure meter - Wikipedia

    en.wikipedia.org/wiki/Respiratory_pressure_meter

    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.

  9. Peak expiratory flow - Wikipedia

    en.wikipedia.org/wiki/Peak_expiratory_flow

    The measurement of peak expiratory flow was pioneered by Martin Wright, who produced the first meter specifically designed to measure this index of lung function. Since the original design of instrument was introduced in the late 1950s, and the subsequent development of a more portable, lower cost version (the "Mini-Wright" peak flow meter ...
