A patient with carbon monoxide poisoning is treated with hyperbaric oxygen that increases the aerial PO2 to 2000 mm Hg. The amount of oxygen dissolved in the aerial blood (in ml/100 ml) is:
Since the solubility of oxygen is 0.003 ml O2/100 ml blood, an aerial PO2 of 2000 mm Hg will increase the concentration of the dissolved oxygen to 6 ml O2/100 ml blood. Note that this actually exceeds the normal aerial-venous difference for the oxygen concentration.
