Figure 1From: Less invasive methods of advanced hemodynamic monitoring: principles, devices, and their role in the perioperative hemodynamic optimizationThe area under the curve (AUC) of the systolic phase is indicative of the SV. The SV is the shaded area under the systolic portion of the arterial pulse waveform. It is calculated as=[area under systolic phase+ aortic compliance] x shape of pressure curve.Back to article page
