Oxygen-Hemoglobin Dissociation Curve

Oxygen-Hemoglobin Dissociation Curve

The HbO2 saturation curve shown here, demonstrates the relationship between the partial pressure of oxygen in the blood and the saturation of hemoglobin with oxygen in blood. In conditions of a right-shift, there is reduced affinity of oxygen to hemoglobin which allows greater delivery of oxygen to the tissues. In conditions of a left-shift, there is a reduced affinity of oxygen to hemoglobin causing a decrease in delivery of oxygen to the tissues.
