WebThe accumulation of 2,3-BPG decreases the affinity of hemoglobin for oxygen. Ultimately, this mechanism increases oxygen release from RBCs under circumstances where it is needed most. This release is potentiated … WebThe relationship between the oxygen tension and hemoglobin saturation is represented by the O 2-Hb dissociation curve. 1 The affinity between O 2 and Hb is reduced with increases in 2,3-diphosphoglyceric acid (DPG), CO 2, and temperature. However, the major regulator of O 2 affinity is plasma pH.

WebArterial oxygen tension (Pao2) is most commonly measured by obtaining an arterial blood sample and by measuring the partial pressure of oxygen with a polarographic electrode. Defining normal parameters for Pa o2 depends on the maturation and age of the patient.
