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 effort measurement;
- generating, using a processor, a PPG waveform based at least in part on the PPG signal;
- analyzing, using the processor, one or more features within the PPG signal;
- determining, using the processor, a second effort measurement based at least in part on the one or more analyzed features;
- comparing, using the processor, the second effort measurement and at least the first effort measurement;
- and
- if the second effort measurement differs from the first effort measurement by a selected value, generating a signal.

A method for monitoring pain management, comprising:
- analyzing, using a processor, one or more features of a PPG signal;
- determining, using the processor, a first effort measurement based at least in part on the one or more analyzed features of the 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 effort measurement based at least in part on the 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 effort measurement and the second effort 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 effort measurement;
- analyze one or more features within the PPG signal;
- determine a second effort measurement based at least in part on the one or more analyzed features of the PPG signal;
- compare the second effort measurement and at least the first effort measurement;
- and
- if the second effort measurement differs from the first effort measurement by a selected value, generate a signal.
