Abstract
A method for monitoring autoregulation includes receiving a blood pressure signal and an oxygen saturation signal, determining a phase difference between the blood pressure signal and the oxygen saturation signal, and determining a patient's autoregulation status based at least in part on a phase difference between the blood pressure signal and the oxygen saturation signal.
Claims20
A method for monitoring autoregulation comprising:
- using a processor for:
- receiving a blood pressure signal and an oxygen saturation signal;
- determining a phase difference between the blood pressure signal and the oxygen saturation signal;
- and
- determining a patient's autoregulation status based at least in part on a phase difference between the blood pressure signal and the oxygen saturation signal.
2 more elements
A non-transitory computer-readable medium having computer executable code stored thereon, the code comprising instructions to:
- receive a blood pressure signal and an oxygen saturation signal;
- determine a phase difference between the blood pressure signal and the oxygen saturation signal;
- and
- determine a patient's autoregulation status based at least in part on a phase difference between the blood pressure signal and the oxygen saturation signal.
1 more element
A system for monitoring autoregulation comprising:
- an oxygen saturation sensor configured to obtain an oxygen saturation signal from a patient;
- a controller comprising a processor configured to:
- receive a blood pressure signal and the oxygen saturation signal;
- determine a phase difference between the blood pressure signal and the oxygen saturation signal;
- and
- determine a patient's autoregulation status based at least in part on a phase difference between the blood pressure signal and the oxygen saturation signal.
