In brief: Fast/deep vs. fast

Tachypnea is a rapid breathing rate (normal is between 12-20 breaths/minute).
Hyperpnea is deeper and more rapid breathing than at rest as occurs, for example with exercise. Neither rapid nor deeper breathing necessarily increases alveolar ventilation which is the amount of air that actually reaches the air sacs to deliver oxygen. If airways are blocked fast and deep breaths dont reach air sacs.
