WebHb (g/dL) = hemoglobin concentration SaO 2 (%) = arterial oxygen saturation in hemoglobin PaO 2 (mm Hg) = arterial oxygen saturation in plasma ( partial pressure of oxygen) 1.34 (mL) = maximum oxygen binding capacity of 1 g of hemoglobin. Normal blood Hb concentration is approximately 15 g/dL. Hemoglobin has an oxygen-binding capacity of 1.34 mL O 2 per gram, which increases the total blood oxygen capacity seventy-fold compared to dissolved oxygen in blood. The mammalian hemoglobin molecule can bind (carry) up to four oxygen molecules.
