Hyperventilation (or hypocapnia) refers to a state of reduced carbon dioxide in the blood. It is usually triggered by breathing too deeply or rapidly, in excess of the metabolic demand. The end result is that alveolar and arterial carbon dioxide (CO2) pressures decrease and blood pH increases. Sustained hyperventilation produces a variety of adverse changes, including a diminished ability for oxygen to pass from the blood to the organism's cells.
