Continuous blood velocity and flow measurements by intravascular elutherm probe.
A device for measuring the mean blood velocity (by means of a thermal equilibrium method) and the intravascular electrical impedance, which determines the mean sectional area of the vessel, have been mounted on the same probe (french catheter 7F). The validity, of the method has been confirmed in vitro and by 100 measurements carried out in dogs and compared with flow measurements by means of the cardio-green method. The correlation coefficient is found to be 0.98.
