System and method for providing blood pressure safe zone indication during autoregulation monitoring

A method for monitoring autoregulation, the method comprising:

• receiving, by one or more processors executing one or more instructions encoded on a memory, one or more physiological signals from a patient;
• determining, by the one or more processors, a correlation-based measure indicative of an autoregulation of the patient based on the one or more physiological signals;
• generating, by the one or more processors, 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;
• designating, by the one or more processors, a blood pressure range encompassing one or more of the bins as a blood pressure safe zone indicative of intact autoregulation;
• providing, by the one or more processors and to a display, a signal to display the autoregulation profile and a first indicator of the blood pressure safe zone;
• and
• providing, by the one or more processors and to the display, a second signal to display a second indicator of a target blood pressure within the blood pressure safe zone for the patient.

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 instructions encoded by the memory, wherein the 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;
• determine if there is sufficient data within the autoregulation profile to designate a patient-specific blood pressure safe zone;
• in response to determining that there is sufficient data, designate a blood pressure range encompassing one or more of the bins as a patient-specific blood pressure safe zone indicative of intact autoregulation utilizing the autoregulation index values and corresponding blood pressure levels;
• and
• provide a first signal to the display to display the autoregulation profile and a first indicator of the patient-specific blood pressure safe zone.
