Abstract
During forced expirations lateral pressures at points within airways equal pleural pressure, and the pressure drop from alveoli to these points approximates the static recoil pressure of the lungs. Maximum expiratory flow is regarded as set by this pressure and the flow-resistance of the airways upstream from these points. The resistance of these segments has a frictional component which increases as lung volume decreases and an accelerative component which decreases as lung volume decreases. The 2 components show systematic changes with age in normal subjects which are interpreted as reflecting differential loss of parenchymal and airway recoll.This publication has 17 references indexed in Scilit:
