Shows changes in the VRV index, VTImin in SVC, and static markers for hypovolemia. Values are normalized to 100 points at the baseline. This means that all variables started at 100%, and the graphs show their changes during the different stages of the experiment. VRV venous return variation index, PPV pulse pressure variations, CO cardiac output, EDP end-diastolic pressure, CVP central venous pressure, S peak systolic peak velocity, SV stroke volume, PCW pulmonary capillary wedge pressure, VTI velocity time integral, MAP mean arterial pressure
