Carboxyhemoglobin-induced changes in the oxygen-hemoglobin dissociation curve. Oxygen-carrying capacity is markedly diminished when carboxyhemoglobin values reach 40% to 50%. In addition, the leftward displacement of the oxygen-hemoglobin dissociation curve makes the oxygen that is bound to hemoglobin less available for delivery to tissues [3].
