A normal blood gas should be memorized using single values rather than a range: pH 7.40, pCO2 40, pO2 100, BE 0, HCO3 24. Our patient's arterial blood gas (ABG) shows that the partial pressure of oxygen (pO2) is slightly low, but satisfactory.n arterial blood gas obtained with the patient breathing room air shows pH 7.35, pCO2 33, pO2 80, BE -7, HCO3 16, O2sat 93%. He is placed on 6 L oxygen by mask, an IV fluid infusion is begun, and antibiotics are administered.
In chronic respiratory acidosis, the PaCO2 is elevated above the upper limit of the reference range, with a normal blood pH (7.35 to 7.45) or near-normal pH secondary to renal compensation and an elevated serum bicarbonate (HCO3â >30 mm Hg).
