Measurements of arterial oxygen saturation were estimated using a pulse oximeter under conditions of reactive hyperaemia in the arms of 10 volunteers. Oxygen saturation measured by pulse oximetry was significantly lower, and venous oxygen saturation measured by co-oximetry was significantly higher, in the hyperaemic arm than in the other arm.
