WebJun 20, 2006 · Background Different lung function equipment and different respiratory manoeuvres may produce different Peak Expiratory Flow (PEF) results. Although the PEF is the most common lung function test, there have been few studies of these effects and no previous study has evaluated both factors in a single group of patients. Methods We … WebThe patient’s FEV 1 is markedly reduced to 0.8 l (33%) while the PEF is relatively preserved at 5.7 l/s (or 340 l/min) which is 80% predicted. As expiration begins (point “a”) there is a rapid increase in expiratory flow until the flow becomes limited by the airway dimensions and peak flow is reached (point “b”).
