  • Abstract
  • Look Inside

We experimentally evaluated the method de-veloped by modified HERD's technique, cardiac output is related to a measure derived from the arterial pressure wave and the heart rate.

Beat-by-beat comparison of stroke volume estimates against estimates based on integration of the output of an electromagnetic flowmeter around the aorta shows a correlation coefficient of 0.829-0.949 under conditions of control and infusion of vesprin, vesprin + lowmolecular weight dextran, vesprin+lowmolcular weight dextran+isoproterenol and noradrenalin.
