WebHypercapnia is the elevation in the partial pressure of carbon dioxide (PaCO2) above 45 mm Hg on Arterial Blood Gas readings. [1] Hypercapnia can eventually cause hypoxaemia due to reduced respiratory drive. Hypercapnia can conversely be caused by long term hypoxaemia which causes the body to compensate leading to increased CO2 in the blood.
