The O2-myoglobin saturation curve has a hyperbolic shape so that it only releases 02 at very high PO2. The Bohr effect is a shift of the hemoglobin saturation curve to the right when temperature decreases, PCO2 decreases and pH increases. Because of the Haldane effect, blood with low PO2 can carry more CO2 than blood saturated in 02. The total amount of O2 in the blood does not depend on the hemoglobin concentration. During hyperventilation, the arterial CO2 content always decreases and the arterial O2 content always increases.
