Forced Expiratory Volume and Forced Vital Capacity
Overview
Forced expiratory volume (FEV) measures how much air a person can exhale during a forced breath. The amount of air exhaled may be measured during the first (FEV1), second (FEV2), and/or third seconds (FEV3) of the forced breath.
Forced vital capacity (FVC) is the total amount of air exhaled during the FEV test.
Forced expiratory volume and forced vital capacity are lung function tests that are measured during spirometry, Opens dialog. Forced expiratory volume is the most important measurement of lung function. It is used to:
