Arterial blood arriving at exercising skeletal muscle has a hemoglobin saturation of about 97%. Within the exercising muscle, local PO2 drops to approximately 15 mmHg. Based on the shape of the oxygen-hemoglobin dissociation curve in this PO2 range, what is the most likely hemoglobin saturation in blood leaving the muscle?
