1. A method for estimating beat-by-beat cardiovascular parameters and variables, comprising:

  • processing two or more cycles of arterial blood pressure to determine a mean arterial blood pressure over each cycle beginning at a beat onset time and an inter-beat variability in blood pressure between the two or more cycles; and

    computing estimates of one or more cardiovascular parameters and variables from the mean arterial blood pressures, the inter-beat variability, and a beat-to-beat averaged Windkessel model of an arterial tree.
