Respiratory acidosis (chronic): pH normal (lower half of normal range), PCO2 raised, bicarbonate high
ОглавлениеIf underventilation, from whatever cause, is sustained beyond a few days, renal tubular reabsorption of bicarbonate will achieve a significant elevation in plasma bicarbonate level, which will correct the acidosis caused by the underventilation. This can be caused by any process that results in sustained hypoventilation (commonly seen in COPD).
