Hypercapnia (from the Greek hyper = “above” or “too much” and kapnos = “smoke”), also known as hypercarbia and CO2 retention, is a condition of abnormally elevated carbon dioxide (CO2) levels in the blood. Carbon dioxide is a gaseous product of the body’s metabolism and is normally expelled through the lungs.
Maybe our lungs are more concerned with being our body’s atmospheric carbon exchange mechanism. Maybe breathing is not as much about oxygen in as carbon out.
