A hemodynamic monitor and corresponding method for determining the requirement for, and if required the nature or extent of, and for monitoring the response to, an intervention by a carer for a subject in order to improve the hydration level and hemodynamic status of the subject during a period or periods of hemodynamic instability includes, firstly, a processor. The processor incorporates software arranged to continuously analyse 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 display means displaying 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 to provide an immediate indication of a change in hemodynamic status and thus the requirement for an intervention. The images also include at least one image representing graphically at least one fluid responsiveness parameter plotted against time to provide an indication of the hydration level and associated ventricular pre load status of the subject to determine the nature or extent of the intervention if required. The images may also include at least one image representing graphically at least one response related parameter compared to the value of the parameter at the point of the intervention to provide an indication of the desired and/or actual response of the subject to an intervention. Trend and acute changes displays may be combined. Specific parameters providing information on the quality of the left ventricle and right heart/venous return/preload may also be derived and displayed.
