Acapnia
Definition
A pathological or physiological condition characterized by an abnormally low concentration or partial pressure of carbon dioxide (CO2) in the arterial blood and tissues. Most frequently caused by alveolar hyperventilation, it leads to a profound disruption of the body's acid-base balance (respiratory alkalosis) and clinically manifests through dizziness, paresthesia, or muscle spasms.
