1. Tidal volume is the volume of air inspired or expired during normal respiration. It is approximately 500 mL.
2. Inspiratory reserve volume is an additional volume of air a person can inspire by a forceful inspiration. It is around 2500 – 3000 mL.
3. Expiratory reserve volume is the additional volume of air a person can be expired by a forceful expiration. This averages 1000 – 1100 mL.
4. Residual volume is the volume of air remaining in lungs even after forceful expiration. This averages 1100 – 1200 mL.
