EVC - expiratory vital capacity
The volume change of the lung between a full inspiration to total lung capacity and a maximal expiration to residual volume.
The expiratory vital capacity is assessed during an expiratory maneuver, which is not performed forcefully. This index is called the ‘slow vital capacity’ in Anglo-American literature. The selection criteria are the same as for the IVC.
