Abstract

According to various embodiments, a regional oximetry sensor may include a light emitting element configured to emit light, a light detector configured to receive the light, and a memory device configured to store a baseline. The baseline stored by the memory device enables a regional oximetry monitor to display the baseline on a display of the regional oximetry monitor.

Claims

1. A regional oximetry sensor, comprising:

a light emitting element configured to emit light;

a light detector configured to receive the light; and

a memory device configured to store a baseline based at least in part on the received light, wherein the baseline stored by the memory device enables a regional oximetry monitor to display the baseline on a display of the regional oximetry monitor.

2. The sensor of claim 1, wherein the baseline comprises a plurality of regional oxygen saturation (rSO₂) measurements obtained by the regional oximetry sensor over a period.

3. The sensor of claim 1, wherein the regional oximetry sensor is configured to determine an average rSO₂ value of a plurality of rSO₂ measurements obtained by the regional oximetry sensor over a period as the baseline.

4. The sensor of claim 1, wherein the regional oximetry sensor is configured to retain the baseline in the memory device when the regional oximetry sensor is disconnected from the regional oximetry monitor or is removed from a patient.

5. The sensor of claim 1, comprising a first light detector configured to receive light that has traveled along a first path, and a second light detector configured to receive light that has traveled along a second path different from the first path.

6. The sensor of claim 1, wherein the regional oximetry sensor is configured to store a timestamp or a label with each of a plurality of baselines stored in the memory device.

7. The sensor of claim 1, comprising a sensor removal device configured to detect removal or dislodging of the regional oximetry sensor from a patient, and label the detected removal or dislodging in the baseline.

8. The sensor of claim 1, wherein the memory device is configured to store a patient identification code.

9. A regional oximetry system, comprising:

a regional oximetry sensor, comprising;

a light emitting element configured to emit light;

a light detector configured to receive the light; and

a memory device configured to store a baseline, wherein the baseline relates to a plurality of regional oxygen saturation (rSO₂) measurements based at least in part on the received light over a period; and

a regional oximetry monitor configured to read the baseline from the regional oximetry sensor and to display the baseline on a display of the regional oximetry monitor.

10. The system of claim 9, wherein the baseline comprises a plurality of rSO₂ measurements obtained by the regional oximetry sensor over a period.

11. The system of claim 9, wherein the regional oximetry sensor or the regional oximetry monitor is configured to determine an average rSO₂ value of the plurality of rSO₂ measurements as the baseline.

12. The system of claim 9, wherein the regional oximetry sensor is configured to retain the baseline in the memory device when the regional oximetry sensor is disconnected from the regional oximetry monitor or is removed from a patient.

13. The system of claim 9, wherein the regional oximetry monitor is configured to prompt a caregiver for input prior to reading the baseline from the regional oximetry sensor.

14. The system of claim 9, wherein the regional oximetry monitor is configured to erase the baseline from the memory device of the regional oximetry sensor.

15. The system of claim 9, wherein the memory device is configured to store a patient identification code, and the regional oximetry monitor is configured to read the patient identification code from the regional oximetry sensor and to display the patient identification code on the display.

16. A regional oximetry monitor, comprising:

a drive circuit configured to provide signals to circuitry of a regional oximetry sensor;

a first circuit configured to read a baseline from a memory of the regional oximetry sensor, wherein the baseline relates to a first plurality of regional oxygen saturation (rSO₂) measurements obtained by the regional oximetry sensor over a first period; and

a second circuit configured to display the baseline on a display of the regional oximetry monitor.

17. The monitor of claim 16, wherein the first circuit is configured to determine an average rSO₂ value of the baseline, and the second circuit is configured to display the average rSO₂ value as the baseline on the display.

18. The monitor of claim 16, wherein the regional oximetry monitor is configured to prompt a caregiver for input prior to displaying the baseline on the display.

19. The monitor of claim 16, wherein the second circuit is configured to display on the display a second plurality of rSO₂ measurements obtained by the regional oximetry sensor over a second period different from the first period together with the baseline.

20. The monitor of claim 16, wherein the first circuit is configured to erase the baseline from the memory of the regional oximetry sensor.
