A hemodynamic monitor including a processor incorporating software arranged to continuously analyze and process a blood pressure or arterial volume/plethysmographic signal obtained from the subject in order to derive a plurality of complementary parameters throughout the monitoring of the subject. The monitor also incorporates a display arranged to interact with the processor to display images representing the derived plurality of complementary parameters. The images include at least one image representing graphically at least one stress related hemodynamic parameter plotted against time and at least one image representing graphically at least one fluid responsiveness parameter plotted against time.
