19. A device comprising a computer-readable medium having executable instructions stored thereon, configured to be executable by processing circuitry for causing the processing circuitry to:
receive one or more physiological signals from a patient;
determine a correlation-based measure indicative of an autoregulation of the patient based on the one or more physiological signals;
generate an autoregulation profile of the patient based on autoregulation index values of the correlation-based measure, wherein the autoregulation profile comprises the autoregulation index values sorted into bins corresponding to different blood pressure ranges;
designate a blood pressure range encompassing one or more of the bins as a blood pressure safe zone indicative of intact autoregulation;
provide a first signal to the display to display the autoregulation profile and a first indicator of the blood pressure safe zone; and
provide a second signal to the display to display a second indicator of a target blood pressure within the blood pressure safe zone for the patient.
