As the hematocrit was decreased, the amount of CO2 released per mol of hemoglobin increased, while the change in intracellular bound CO2 concentration decreased. That is, the intracellular bound CO2 became higher in the lower hematocrit blood than in the higher hematocrit one. WebCarbon Monoxide The binding of one CO molecule to hemoglobin increases the affinity of the other binding spots for oxygen, leading to a left shift in the dissociation curve. This shift prevents oxygen unloading in peripheral tissue and therefore the oxygen concentration of the tissue is much lower than normal. shannon cotter ey
