ERV expiratory reserve volume
FRC functional residual capacity
EVC expiratory vital capacity
IVC inspiratory vital capacity
TLC total lung capacity

RV - residual volume

The volume of the lung after maximal exhalation started from the functional residual capacity.

In patients with airway obstruction an FVC maneuver usually ends at a higher lung volume than a maximal expiration started from FRC level; only in the latter instance should end-expiratory volume be called RV.

RV grows faster than TLC in adolescents
