Erv is reduced
WebThe reserve volume is the amount of air that remains in the lungs and passageways after a maximal expiration. Vital capacity is the total of the tidal volume, inspiratory reserve volume, and expiratory reserve volume. In a normal healthy adult lung, the vital capacity usually ranges from 3.5 to 5.5 L of air.
