Calculation of average relative blood flow (rBF, in %) vs. mean arterial pressure (MAP). An example time trace for (A) rBF and (B) MAP for a single day of monitoring are shown. Using these time traces, (C) rBF is plotted against MAP and an average rBF value at each MAP is calculated (red circle). (D) An averaged rBF vs. MAP curve is generated for both the right (red circle) and left hemisphere (blue circle). Using the data in (D), |ΔrBF_MAP| (in %/mmHg) is plotted against MAP in (E). ASYM_rBF, averaged |ΔrBF_MAP| of this monitoring day for a patient is shown on the upper right corner.
