Forced Expiratory Flow and Volume

Measure the average flow over specified portions of the spirometry curve. The spirometry maneuver requires the subject to inhale to total lung capacity and then exhale forcefully to residual volume.

Integrate forced expiratory flow (FEF) to obtain forced expiratory volume (FEV). AcqKnowledge generates the spirometry curve via an X/Y plot of expired volume versus expired flow. The FEF values can be measured directly on the spirometry curve at the standard 25%, 50% and 75% volume points.
