Hypercarbia is the term used to describe the inability to eliminate carbon dioxide from the body by exhalation. When carbon dioxide cannot be eliminated, an increasingly urgent sensation to breathe develops. If airflow is not restricted, the rate and depth of breathing reflexively increase. At very high levels of carbon dioxide, a person can become unresponsive and the pH of the blood can become dangerously acidic. | Hypercarbia is the term used to describe the inability to eliminate carbon dioxide from the body by exhalation.
