<prompt> 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 ml100 ml is:2346  <response>: Since the solubility of oxygen is 0.003 ml O2100 ml blood, an aerial PO2 of 2000 mm Hg will increase the concentration of the dissolved oxygen to 6 ml O2100 ml blood. Note that this actually exceeds the normal aerial-venous difference for the oxygen concentration.
