Medical Definition of inspiratory reserve volume. : the maximal amount of additional air that can be drawn into the lungs by determined effort after normal inspiration — compare expiratory reserve volume.
The ERV is the maximum amount of air that can be expelled from the lungs after a normal exhalation. The volume remaining in the lungs after a normal exhale is the functional residual capacity (FRC). The volume of air in the lungs that cannot be expelled is the residual volume, or RV. Therefore, ERV = FRC - RV.
The inspiratory reserve volume , about 3,100 mL, is the additional air that can be forcibly inhaled after the inspiration of a normal tidal volume. The expiratory reserve volume , about 1,200 mL, is the additional air that can be forcibly exhaled after the expiration of a normal tidal volume.
