Ontology: Hyperventilation (C0020578)

Definition (NCI) Abnormally prolonged, rapid, and deep breathing.
Definition (NCI_FDA) Abnormally prolonged, rapid, and deep breathing.
Definition (MSH) A pulmonary ventilation rate faster than is metabolically necessary for the exchange of gases. It is the result of an increased frequency of breathing, an increased tidal volume, or a combination of both. It causes an excess intake of oxygen and the blowing off of carbon dioxide.
