Abstract
A method and device for monitoring vascular access is described. A field coil is placed at a location on an extracorporeal circulation loop connected to the vascular system of a patient, and an induction coil is placed at another different location. A voltage is supplied to the field coil, inducing an electric current in the blood. The current induces a voltage in the induction coil. Monitoring the voltage in the induction coil reveals if vascular access is defective.
