CO₂is carried by hemoglobin as carbamino-hemoglobin (about 20-25 percent). This binding is related to the partial pressure of CO₂. pO₂is a major factor that could affect this binding. When pCO₂is high and pO₂is low as in the tissues, more binding of carbon dioxide occurs whereas, when the pCO₂is low and pO₂is high as in the alveoli, dissociation takes place.
