Vice versa, it is true that a high concentration of CO 2 facilitates dissociation of oxyhemoglobin, though this is the result of two distinct processes (Bohr effect and ...
The Haldane effect: most carbon dioxide is carried by the blood as bicarbonate, and deoxygenated hemoglobin promotes the production of bicarbonate. Increasing the amount of oxygen in the blood by administering supplemental oxygen reduces the amount of deoxygenated hemoglobin, and thus reduces the capacity of blood to carry carbon dioxide.
