WebRespiratory acidosis revealed by the ABG measurement (eg, pH < 7.35 and PCO2 > 50) confirms the diagnosis. Patients with chronic ventilatory failure often have quite elevated PCO2 (eg, 60 to 90 mm Hg) at baseline, typically with a pH that is only slightly acidemic. WebRespiratory acidosis is a condition that occurs when your lungs can’t remove all of the carbon dioxide produced by your body. This causes the blood and other body fluids to become too acidic. Causes There are many causes of respiratory acidosis, including: Airway diseases, such as asthma and COPD
