Forced expiratory volume (FEV) can be defined as the amount of air that can be exhaled by an individual during a forced breath. The forced expiratory measurements measure the expiratory volume, flow, and capacities. The condition of the airways is depicted by different pulmonary mechanic measurements such as FEF25-75% and FEF200-1200.
