Residual volume (1100-1200 mL) or RV is the volume of air that always remains in the lungs after forceful expiration.
Inspiratory Reserve Volume (IRC) is 2500-3000 mL. It is an additional amount of air that can be inspired forceful after a normal inspiration.
Vital capacity (VC) is 4000-4600 mL. It is the total maximum volume of air that can be inspired or expired. It is the sum total of tidal volume, inspiratory reserve volume and expiratory reserve volume.
Expiratory Reserve Volume (ERV) is 1000-1100 mL. It is the extra amount of air that can be expelled after a normal expiration, i.e., forced expiration.
Inspiratory capacity (IC) is 3000-3500 mL. It is the total volume of air that can be inhaled after a normal expiration. It includes tidal volume and inspiratory reserve volume.
