<unk>  occurs when carbon dioxide production exceeds the elimination mainly due to alveolar hypoventilation.<unk>  is associated with concurrent increases in Paco2, decreases in pH and compensatory increases in blood HCO3- concentration.Respiratory acidosis can be acute or chronic, with initial metabolic compensation to increase HCO3- concentrations by intracellular buffering. Chronic<unk>  results in longer lasting increases in renal reabsorption of HCO3-. Alveolar hypoventilation and resulting<unk>  may also be associated with hypoxemia, especially evident when patients are inspiring room air (20.9% O2).
