Hypercapnia refers to excess carbon dioxide in the arterial blood, which can be caused by hypoventilation (reduced breathing rate) or other factors that result in inadequate removal of carbon dioxide. While blowing off carbon dioxide faster than it is being produced can reduce the level of carbon dioxide in the blood, it is not a cause of hypercapnia.
