Respiratory acidosis

Respiratory acidosis is an acid-base disturbance characterized by excess of CO2 in the blood (hypercapnia), indicated by a PaCO2 greater than 45 mm Hg. It results from reduced alveolar ventilation. It can be acute (from a sudden failure in ventilation) or chronic (as in long-term pulmonary disease).
