Difference between Inspiratory and Expiratory Capacity
1. Inspiratory capacity is the total volume of air that can be inhaled after a normal expiration. Expiratory capacity is the total volume of air a person can expire after a normal inspiration.
2. Inspiratory capacity includes tidal volume and the inspiratory reserve volume (IC = TV + IRV). Expiratory capacity includes tidal volume and expiratory reserve volume (EC = TV + ERV).
3. Inspiratory capacity is about 3000 to 3500 mL of air. Expiratory capacity is about 1500 to 1600 mL of air.
