Factors that affect the neonatal oxygen-dissociation curve
The oxygen-dissociation curve of human blood and the effects of changes in the H+ ion concentration, Pco2, temperature, and level of 2,3-diposphoglycerate (2,3-DPG) are depicted above. For fetal hemoglobin, the normal curve (a) is shifted to the left (b).
PCO2: partial pressure of carbon dioxide; PO2: partial pressure of oxygen; O2: oxygen.
