All the air that can be inspired from resting

position

Volume of air remaining in the lungs after normal

expiration

All the air that you are capable of moving

All the air present in the lungs after maximal

inspiration

Volume of air inspired during quiet breathing / volume of air inspired or expired normally

Additional volume that can be inspired above Vt

Additional volume that can be expired below Vt

Volume of air remaining after maximum expiration

? = VT + IRV

• Inspiratory capacity (IC)

• expiratory capacity (EC)

• vital capacity (VC)

• residual volume (RV)

? = ERV + RV

• vital capacity (VC)

• Expiratory volume ( EV)

• Functional residual capacity

• total lung capacity (TLC)
