Forced expiratory volume over 1 second (FEV1) is a dynamic measure of flow used in formal spirometry. It represents a truer indication of airway obstruction than does peak flow rate. Although peak flow rate usually correlates well with FEV1, this correlation decreases in patients with asthma as airflow diminishes.
