System and method of monitoring autoregulation
First Claim
Patent Images
1. A method for monitoring autoregulation, the method comprising:
- receiving, by one or more processors, blood pressure data and oxygen saturation data from a patient;
detecting, by the one or more processors, a step change in a blood pressure of the patient based on the blood pressure data;
fitting, by the one or more processors, a dynamic model to the blood pressure data and the oxygen saturation data to determine one or more parameters of the dynamic model indicative of autoregulation only after the step change in the blood pressure is detected, wherein the dynamic model indicates a response of oxygen saturation to a change in blood pressure; and
determining, by the one or more processors, the patient'"'"'s autoregulation status based on the one or more parameters.

Abstract
A method for monitoring autoregulation includes using a processor for receiving blood pressure data and oxygen saturation data from a patient, fitting a dynamic model to the blood pressure data and the oxygen saturation data to determine one or more parameters of the dynamic model indicative of autoregulation, and determining the patient'"'"'s autoregulation status based on the one or more parameters.

10. A non-transitory computer-readable medium having computer executable code stored thereon, the code comprising instructions that, when executed by one or more processors, cause the one or more processors to:
-
receive blood pressure data and oxygen saturation data from a patient; detect a step change in a blood pressure of the patient based on the blood pressure data; fit a dynamic model to the blood pressure data and the oxygen saturation data to determine one or more parameters of the dynamic model indicative of autoregulation only after the step change in the blood pressure is detected, wherein the dynamic model indicates a response of oxygen saturation to a change in blood pressure; and determine the patient'"'"'s autoregulation status based on the one or more parameters. - View Dependent Claims (11, 12)

13. A system for monitoring autoregulation, the system comprising:
-
an oxygen saturation sensor configured to obtain oxygen saturation data from a patient; and a controller comprising one or more processors configured to; receive blood pressure data indicative of blood pressure of the patient and receive the oxygen saturation data; detect a step change in a blood pressure of the patient based on the blood pressure data; fit a dynamic model to the blood pressure data and the oxygen saturation data to determine one or more parameters of the dynamic model indicative of autoregulation only after the step change in the blood pressure is detected, wherein the dynamic model indicates a response of oxygen saturation to a change in blood pressure; and determine the patient'"'"'s autoregulation status based on the one or more parameters. - View Dependent Claims (14, 15, 16, 17, 18, 19)
