1. A system for displaying information about cardiac output and/or total peripheral resistance, comprising:

  • a display;

    a processor; and

    a memory storing computer-executable instructions which, when executed by the processor, cause the processor to;

    process two or more cycles of arterial blood pressure information 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,compute time series of estimates of cardiac output and/or total peripheral resistance based on the mean arterial blood pressures, the inter-beat variability, and a computational model of an arterial tree, andcause the display of the time series of estimates.
