A flow limiting compressed airway segment, such as occurs during a forced expiration, does not occur during inspiration. Obviously, in the case of diffuse airway obstruction, such as in COPD, the increased airway resistance may limit inspiratory flow somewhat. Lung elastic recoil does not play part in inspiratory flow (apart from being a component of pleural pressure); on that account, in the case of pulmonary emphysema but no significant peripheral airway obstruction, inspiratory flow will be normal. This is why in such patients the FEV1 is low, but the FIV1 within normal limits.
The animation depicts schematically airway dimensions during forced inspirations and expirations.
