A sensor (10)includes a catheter (12) with a sensor end (14) and an instrumentation end (16), at least one pair of electrodes (24, 26) with associated leads (20, 22) mounted near the sensor end and spaced apart by a predetermined distance and a conductivity measuring and processing network (30) selectively connected to the leads at the instrumentation end to provide signals representative of blood vessel characteristics, e.g. continuous cardiac output, stroke volume on a beat-to-beat basis. |
