Forced expiratory volume is the volume of air that is forced out in a deep breath. It is used to diagnose asthma and chronic obstructive pulmonary disease is a measure of pulmonary function have lower FEV .
In asthma (an obstructive lung disorder) the forced expiratory volume in 1 second (FEV1) is usually decreased, the forced vital capacity (FVC) is usually normal and the ratio FEV1/FVC is decreased. In restrictive disorders the FEV1 and FVC are both decreased, leaving a normal FEV1/FVC.
