## Respiratory Volumes and Capacities * **Tidal Volume (TV)**: Volume of air inspired or expired during a normal respiration. It is approximately 500 mL, i.e., a healthy man can inspire or expire approximately 6000 to 8000 mL of air per minute. * **Inspiratory Reserve Volume (IRV)**: Additional volume of air a person can inspire by a forcible inspiration. This averages 2500 mL to 3000 mL. * **Expiratory Reserve Volume (ERV)**: Additional volume of air a person can expire by a forcible expiration. This averages 1000 mL to 1100 mL.
