<h3>What is hyperventilation?</h3>
Hyperventilation is rapid breathing in of oxygen and breathing out of carbondioxide.
The various causes of hyperventilation include the following:
When a person hyperventilates they exhale more carbon dioxide than normal. As a result the carbon dioxide concentration in the blood decreases.
While the corresponding drop in H3O+ concentration causes an increase in pH.
