WebMaximal inspiratory airflow at 50% of forced vital capacity (MIF 50% FVC) is greater than maximal expiratory airflow at 50% FVC (MEF 50% FVC) because dynamic compression of the airways occurs during exhalation. (B) Obstructive disorder (eg, emphysema, asthma). Although all airflow is diminished, expiratory prolongation predominates, and MEF < MIF.
