Acidosis, Respiratory (C0001127)

Definition (NCI_FDA) A state due to excess retention of carbon dioxide in the body.
Definition (NCI) Acid base imbalance resulting from an accumulation of carbon dioxide secondary to hypoventilation.
Definition (CSP) excess retention of carbon dioxide in the body resulting from ventilatory impairment.
Definition (MSH) Respiratory retention of carbon dioxide. It may be chronic or acute.
