WebNov 2, 2004 · In restrictive diseases, the maximum flow rate is reduced, as is the total volume expired. The flow is abnormally high in the latter part of expiration because of increased recoil. In obstructive diseases, the flow rate is very low in relation to lung volume, and a scooped out appearance is often seen following the point of maximal flow. WebAbstract. Background: Patterns of pulmonary function tests (PFTs) and flow-volume loops among patients with clinically important tracheobronchomalacia (TBM) are not well described. Small studies suggest 4 main flow-volume loop morphologies: low maximum forced expiratory flow, biphasic expiratory curve, flow oscillations, and notching.
