Hyperventilation corresponds to which description?

Explanation:
Hyperventilation means breathing more air than the body needs, typically with both an increased rate and greater depth. This rapid, deep breathing drives off carbon dioxide, leading to respiratory alkalosis. Distinguishing it from other patterns: rapid breathing alone is tachypnea, which may be fast but not necessarily deep; slow breathing is bradypnea; a Cheyne-Stokes pattern is a cycle of waxing and waning breaths with pauses, not simply consistently increased ventilation. So the description that fits hyperventilation is fast, deep breathing that exceeds metabolic needs, producing low CO2.
