compensatory metabolic acidosis. A normal arterial blood gas in a gravid woman is a pH of 7.40 to 7.47, with a Paco2 of 30 to 32 mm Hg and a normal to slightly elevated Pao2. The kidneys compensate partially for the alkalosis by increasing renal bicarbonate excretion, which keeps serum HCO3 levels between 18 and 21 mEq/L (base deficit, 3-4 mEq/L).

and bicarbonate (HCO3-). pH reflects the overall H+ concentration in body fluids. Increasing the number of H+ in the blood will lower pH (more acidic); while decreasing the number of H+ will increase pH (more alkaline). Blood is slightly alkaline—for normal enzyme/cell function and metabolism, pH must remain within a narrow range.

pulse oximetry is no substitute for arterial blood gas analysis. Pulse oximetry is solely a measure of oxygen saturation and gives no indication about blood pH, carbon dioxide or bicarbonate concentrations. Arterial puncture Blood is usually withdrawn from the radial artery as it is easy to palpate and has a good collateral supply.
