Abstract
A method and apparatus in which the blood flow in a fistula is determined by comparing the property of blood entering the fistula to the property of blood being withdrawn from the fistula as the blood in the fistula flows in the direction which is the reverse of the predominant flow. A property marker fluid is injected into the blood entering the fistula in order to alter the property of the blood. Aseptic conditions are maintained during the reversal of the blood flow by maintaining a closed blood loop exterior to the patient. The blood loop closure is maintained by reversing the action of the pump which induces blood flow in the closed blood loop.
