Abstract
A patient monitoring system may include processing circuitry configured to receive an indication of a surgical event, obtain a nociception parameter of a patient, compare the nociception parameter of the patient to a nociception threshold to detect a nociception event, determine whether the surgical event corresponds to the nociception event, and in response to determinizing whether the surgical event corresponds to the nociception event, provide an indication to adjust an amount of analgesic administered to the patient.
Claims20
A method comprising:
- receiving, by processing circuitry, an indication of an occurrence of a surgical event during a period of time;
- setting, by the processing circuitry, a surgical event flag during the period of time based on receiving the indication of the occurrence of the surgical event;
- receiving, by the processing circuitry, a nociception parameter of a patient during the period of time;
- determining, by the processing circuitry, a nociception event based on comparing the nociception parameter of the patient to a nociception threshold;
- and
- providing, by the processing circuitry, an indication to adjust an amount of analgesic administered to the patient based on the surgical event corresponding to the nociception event during the period of time.
A system comprising:
- memory configured to store a nociception threshold;
- and
- processing circuitry configured to:
- receive an indication of an occurrence of a surgical event during a period of time;
- set a surgical event flag during the period of time based on receiving the indication of the occurrence of the surgical event;
- receive a nociception parameter of a patient during the period of time;
- determine a nociception event based on comparing the nociception parameter of the patient to the nociception threshold;
- and
- provide an indication to adjust an amount of analgesic administered to the patient based on determining that the surgical event corresponds to the nociception event during the period of time.
A non-transitory computer readable storage medium comprising instructions that, when executed, cause processing circuitry to:
- receive an indication of an occurrence of a surgical event during a period of time;
- set a surgical event flag during the period of time based on receiving the indication of the occurrence of the surgical event;
- receive a nociception parameter of a patient;
- determine a nociception event based on comparing the nociception parameter of the patient to a nociception threshold;
- and
- provide an indication to adjust an amount of analgesic to administer to the patient based on determining that the surgical event corresponds to the nociception event during the period of time.
