Inspiratory Capacity (IC) is the maximum amount of air that can be inspired after a normal expiration, IC, = TV +IRV. It is 3600 mL in adult male and 2400 mL in the adult female.
Residual Volume (RV) is the amount of air remaining in the lungs after a forced exhalation. Its average value is 1200 mL and 1000 mL in adult male and female respectively.
