Inspiratory reserve volume is additional volume of air a person can inspire by a forceful inspiration. It is around 2500 - 3000 mL. Expiratory reserve volume is additional volume of air a person can be expired by a forceful expiration. This averages 1000 - 1100 mL. Residual volume is volume of air remaining in lungs even after forceful expiration. This averages 1100 - 1200 mL.
