Forced Expiratory Flow (FEF) is the flow (or speed) of air coming out of the lung during the middle portion of a forced expiration, given at specific specific intervals, generally defined by what fraction remains of the functional vital capacity (FVC).
It can be given at discrete times, generally defined by what fraction remains of the functional vital capacity (FVC). Forced Expiratory Flow (FEF) is the flow (or speed) of air coming out of the lung during the middle portion of a forced expiration.
