Abstract
Processing circuitry may receive one or more signals of a patient. The processing circuitry may determine an autoregulation status of the patient based at least in part on the one or more signals. The processing circuitry may output, for display at an output device, a graphical user interface (GUI) that includes an indication of the autoregulation status of the patient and an indication of a lower limit of autoregulation (LLA) value, wherein the GUI does not include an indication of an upper limit of autoregulation (LLA) value.
Claims14
A method comprising:
- receiving, by processing circuitry, a blood pressure signal comprising blood pressure values of a patient;
- determining, by the processing circuitry, an autoregulation status of the patient based at least in part on the blood pressure signal;
- displaying a graphical user interface (GUI) that includes a graph of the blood pressure values over time and an indication on the graph of the autoregulation status of the patient and an indication of a lower limit of autoregulation (LLA) at a first time, the LLA comprising a first blood pressure value below which autoregulation is impaired, wherein the autoregulation status of the patient on the graph includes a first graphical indication of a safe zone associated with an intact autoregulation state of the patient above the LLA and a second graphical indication of an unsafe zone associated with an impaired autoregulation state of the patient below the LLA;
- determining, by the processing circuitry, a change in the LLA at a second, subsequent time;
- and
- in response to determining the change in the LLA, updating the GUI, by the processing circuitry, wherein updating the GUI comprises visually changing:
- the indication of the LLA on the graph to an updated value of the LLA based on the change, and
- a portion of the first graphical indication of the safe zone that is prior to the change in the LLA, a portion of the second graphical indication of the unsafe zone that is prior to the change in the LLA, or both.

A system comprising:
- a blood pressure sensor;
- and
- processing circuitry configured to:
- receive, from the blood pressure sensor, a blood pressure signal comprising blood pressure values of a patient;
- determine an autoregulation status of the patient based at least in part on the blood pressure signal;
- display a graphical user interface (GUI) that includes a graph of the blood pressure values over time and an indication on the graph of the autoregulation status of the patient and an indication of a lower limit of autoregulation (LLA) at a first time, the LLA comprising a blood pressure value below which autoregulation is impaired, wherein the autoregulation status of the patient on the graph includes a first graphical indication of a safe zone associated with an intact autoregulation state of the patient above the LLA and a second graphical indication of an unsafe zone associated with an impaired autoregulation state of the patient below the LLA;
- determine a change in the LLA at a second, subsequent time;
- and
- in response to determining the change in the LLA, update the indication of the LLA and update a portion of the first graphical indication of the safe zone that is prior to the change in the LLA, a portion of the second graphical indication of the unsafe zone that is prior to the change in the LLA, or both.

A non-transitory computer readable storage medium comprising instructions that, when executed, cause processing circuitry to:
- receive a blood pressure signal comprising blood pressure values of a patient;
- determine an autoregulation status of the patient based at least in part on the blood pressure signal;
- display a graphical user interface (GUI) that includes a graph of the blood pressure values over time and an indication on the graph of the autoregulation status of the patient and an indication of a lower limit of autoregulation (LLA) at a first time, the LLA comprising a first blood pressure value below which autoregulation is impaired, wherein the autoregulation status of the patient on the graph includes a first graphical indication of a safe zone associated with an intact autoregulation status of the patient above the LLA and a second graphical indication of an unsafe zone associated with an impaired autoregulation status of the patient below the LLA;
- determine a change in the LLA at a second, subsequent time;
- and
- in response to determining the change in the LLA, update the indication of the LLA and update a portion of the first graphical indication of the safe zone that is prior to the change in the LLA.
