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

  • processing one or more cycles of arterial blood pressure to determine intra-beat and inter-beat variability in blood pressure; and

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