Systems and Methods for Optimizing Autoregulation Measurements
First Claim
1. A method for monitoring autoregulation of a patient, comprising:
- using a processor for;
receiving a blood pressure signal and a regional oxygen saturation signal from a patient;
determining one or more pairs of linear correlation lines between the blood pressure signal and the regional oxygen saturation signal based on one or more bins, wherein each of the one or more bins comprises one or more regional oxygen saturation values derived from the regional oxygen saturation signal;
determining a value indicative of the patient'"'"'s autoregulation status based on a first pair of linear correlation lines selected from the one or more pairs of linear correlation lines; and
providing a signal indicative of the patient'"'"'s autoregulation status to an output device.

Abstract
A method for monitoring autoregulation includes receiving a blood pressure signal and a regional oxygen saturation signal from a patient. The method also includes determining one or more pairs of linear correlation lines between the blood pressure signal and the regional oxygen saturation signal based on one or more bins. Each of the one or more bins includes one or more regional oxygen saturation values derived from the regional oxygen saturation signal. The method also includes determining a value indicative of the patient'"'"'s autoregulation status based on a first pair of linear correlation lines selected from the one or more pairs of linear correlation lines and providing a signal indicative of the patient'"'"'s autoregulation status to an output device.
