(March 2009). The oxygenâhemoglobin dissociation curve, also called the oxyhemoglobin dissociation curve or oxygen dissociation curve (ODC), is a curve that plots the proportion of hemoglobin in its saturated (oxygen-laden) form on the vertical axis against the prevailing oxygen tension on the horizontal axis.n its most simple form, the oxyhemoglobin dissociation curve describes the relation between the partial pressure of oxygen (x axis) and the oxygen saturation (y axis). Hemoglobin's affinity for oxygen increases as successive molecules of oxygen bind.
So, the curve has an s-shape because, at lower PO2s, oxygen binds to hemoglobin at a high rate, and this slows down as hemoglobin become more saturated. At PO2s above 60 the curve is relatively flat, meaning that the oxygen content of the blood will not change much with subsequent increases in PO2. Shift to the left: The curve shifts to the left when hemoglobin has an increased affinity for oxygen, and has an easier time making the bond with oxygen. 2  Higher SpO2 for a given PO2. 3  Hemoglobin is more likely to cling to O2 and not let go (activity is minimal). 4  Think Cold.
