1. A monitor for monitoring autoregulation, the monitor comprising:
a display;
a memory encoding one or more processor-executable instructions; and
one or more processors configured to access and execute the one or more processor-executable instructions encoded by the memory, wherein the one or more processor-executable instructions, when executed, cause the one or more processors 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;
provide a first signal to the display or another output device to provide an indicator of a distance of a current blood pressure from a target blood pressure; and
provide a second signal to the display to display the autoregulation profile.
