Abstract
The present disclosure relates to systems and methods for monitoring pain management using measurements of physiological parameters based on a PPG signal. A reference physiological parameter may be compared against a later measurement to identify a change in condition that may indicate a pain management problem.
Claims20
A method for monitoring pain management, comprising:
- receiving, at a processor, a first blood pressure measurement;
- detecting a PPG signal with a sensor comprising at least one emitter and at least one detector, the sensor being coupled to the processor;
- determining, using the processor, a second blood pressure measurement based at least in part on the detected PPG signal;
- comparing, using the processor, the second blood pressure measurement and at least the first blood pressure measurement;
- and
- if the second blood pressure measurement differs from the first blood pressure measurement by a selected value, generating a signal.

A method for monitoring pain management, comprising:
- detecting a PPG signal with a sensor comprising at least one emitter and at least one detector;
- determining, using a processor coupled to the sensor, a first blood pressure measurement based at least in part on the detected PPG signal;
- receiving information at the processor indicating that pain management or sedation has been administered to a patient;
- determining, using the processor, a second blood pressure measurement based at least in part on a second PPG signal at a time after the pain management or sedation has been administered to a patient;
- and
- determining, using the processor, an effectiveness of the pain management or sedation based at least in part on a comparison of the first blood pressure measurement and the second blood pressure measurement.
3 more elements
A system for monitoring pain management, comprising:
- a sensor having at least one emitter and at least one detector configured to detect a PPG signal, the sensor coupled to a processor and control circuitry configured to:
- receive a first blood pressure measurement;
- determine a second blood pressure measurement based at least in part on the detected PPG signal;
- compare the second blood pressure measurement and at least the first blood pressure measurement;
- and
- if the second blood pressure measurement differs from the first blood pressure measurement by a selected value, generate a signal.
