1. A vascular impedance measurement instrument, comprising:

  • means for measuring an arterial blood pressure of a patient and producing a corresponding series of digitized data samples representing a waveform of the arterial blood pressure of the patient;

    means for determining a mean arterial pressure of the patient from the sample series;

    means for determining a cardiac output measurement value for the patient from the sample series and from clinically derived patient data;

    means for determining for the patient one or more parameters of a vascular impedance model from the sample series and from the cardiac output value; and

    means for displaying the one or more parameters.
