flow-volume curve

flow-vol·ume curve

the graph produced by plotting the instantaneous flow of respiratory gas against the simultaneous lung volume, usually during maximal forced expiration.

flow-volume curve

a graphic of the instantaneous rate of airflow during a forced expiration. It is plotted as a function of the volume. It may be a maximum expiratory flow-volume curve or a partial expiratory flow-volume curve.
