Abstract

The present disclosure describes the derivation and measurement of a fractional oxygen saturation measurement. In one embodiment, a system includes an optical sensor and a processor. The optical sensor can emit light of multiple wavelengths directed at a measurement site of tissue of a patient, detect the light after attenuation by the tissue, and produce a signal representative of the detected light after attenuation. The processor can receive the signal representative of the detected light after attenuation and determine, using the signal, a fractional oxygen saturation measurement based on two or more different measures of fractional oxygen saturation.

Claims (34)

1. A patient monitoring apparatus comprising:

a housing;

a memory device configured to store a signal generated by a noninvasive physiological sensor that monitors a patient, the signal being responsive to a physiological condition of the patient; and

one or more hardware processors in communication with the memory device, the one or more hardware processors being configured to:

determine a functional oxygen saturation measurement, a methemoglobin measurement, and a carboxyhemoglobin measurement from the signal,

determine a dishemoglobin measurement from the signal without using the methemoglobin measurement and the carboxyhemoglobin measurement,

determine a first fractional oxygen saturation measurement from the signal using a first algorithm, the first algorithm using as inputs the functional oxygen saturation measurement, the methemoglobin measurement, and the carboxyhemoglobin measurement,

determine a second fractional oxygen saturation measurement from the signal using a second algorithm different from the first algorithm, the second algorithm using as inputs the functional oxygen saturation measurement and the dishemoglobin measurement, and

determine an output fractional oxygen saturation measurement for presentation to a user from the first fractional oxygen saturation measurement and the second fractional oxygen saturation measurement.

2. The patient monitoring apparatus of claim 1 , wherein the one or more hardware processors are configured to determine the output fractional oxygen saturation measurement to be either the first fractional oxygen saturation measurement or the second fractional oxygen saturation measurement.

3. The patient monitoring apparatus of claim 1 , wherein the first fractional oxygen saturation measurement is associated with a first confidence value and the second fractional oxygen saturation measurement is associated with a second confidence value, and the one or more hardware processors are configured to determine the output fractional oxygen saturation measurement to be either the first fractional oxygen saturation measurement or the second fractional oxygen saturation measurement based at least on a comparison of the first confidence value and the second confidence value.

4. The patient monitoring apparatus of claim 1 , wherein the one or more hardware processors are configured to determine the output fractional oxygen saturation measurement from a comparison of the first fractional oxygen saturation measurement and the second fractional oxygen saturation measurement.

5. The patient monitoring apparatus of claim 1 , wherein the one or more hardware processors are configured to determine the output fractional oxygen saturation measurement from a combination of the first fractional oxygen saturation measurement and the second fractional oxygen saturation measurement.

6. The patient monitoring apparatus of claim 1 , wherein the one or more hardware processors are configured to:

determine a third fractional oxygen saturation measurement from the signal using a third algorithm different from the first algorithm and the second algorithm, and

determine the output fractional oxygen saturation measurement from a combination of the first fractional oxygen saturation measurement, the second fractional oxygen saturation measurement, and the third fractional oxygen saturation measurement.

7. The patient monitoring apparatus of claim 6 , wherein the one or more hardware processors are configured to determine the third fractional oxygen saturation measurement from the signal without using the functional oxygen saturation measurement, the methemoglobin measurement, the carboxyhemoglobin measurement, and the dishemoglobin measurement.

8. The patient monitoring apparatus of claim 1 , further comprising a display configured to present the output fractional oxygen saturation measurement to the user.

9. A patient monitoring method comprising:

storing, by a memory device, a signal generated by a noninvasive physiological sensor monitoring a patient, the signal being responsive to a physiological condition of the patient;

determining, by one or more hardware processors, a functional oxygen saturation measurement, a methemoglobin measurement, and a carboxyhemoglobin measurement from the signal;

determine a dishemoglobin measurement from the signal without using the methemoglobin measurement and the carboxyhemoglobin measurement;

determining, by the one or more hardware processors, a first fractional oxygen saturation measurement from the signal using a first algorithm, the first algorithm using as inputs from the functional oxygen saturation measurement, the methemoglobin measurement, and the carboxyhemoglobin measurement;

determining, by the one or more hardware processors, a second fractional oxygen saturation measurement from the signal using a second algorithm different from the first algorithm, the second algorithm using as inputs the functional oxygen saturation measurement and the dishemoglobin measurement; and

determining, by the one or more hardware processors, an output fractional oxygen saturation measurement for presentation to a user from the first fractional oxygen saturation measurement and the second fractional oxygen saturation measurement.

10. The patient monitoring method of claim 9 , wherein the determining the output fractional oxygen saturation measurement comprises determining the output fractional oxygen saturation measurement to be either the first fractional oxygen saturation measurement or the second fractional oxygen saturation measurement.

11. The patient monitoring method of claim 9 , wherein the first fractional oxygen saturation measurement is associated with a first confidence value and the second fractional oxygen saturation measurement is associated with a second confidence value, and the determining the output fractional oxygen saturation measurement comprises determining the output fractional oxygen saturation measurement to be either the first fractional oxygen saturation measurement or the second fractional oxygen saturation measurement based at least on a comparison of the first confidence value and the second confidence value.

12. The patient monitoring method of claim 9 , wherein the determining the output fractional oxygen saturation measurement comprises determining the output fractional oxygen saturation measurement from a comparison of the first fractional oxygen saturation measurement and the second fractional oxygen saturation measurement.

13. The patient monitoring method of claim 9 , wherein the determining the output fractional oxygen saturation measurement comprises determining the output fractional oxygen saturation measurement from a combination of the first fractional oxygen saturation measurement and the second fractional oxygen saturation measurement.

14. The patient monitoring method of claim 9 , further comprising:

determining, by the one or more hardware processors, a third fractional oxygen saturation measurement from the signal using a third algorithm different from the first algorithm and the second algorithm,

wherein the determining the output fractional oxygen saturation measurement comprises determining the output fractional oxygen saturation measurement from a combination of the first fractional oxygen saturation measurement, the second fractional oxygen saturation measurement, and the third fractional oxygen saturation measurement.

15. The patient monitoring method of claim 14 , wherein the determining the third fractional oxygen saturation measurement comprises determining the third fractional oxygen saturation measurement from the signal without using the functional oxygen saturation measurement, the methemoglobin measurement, the carboxyhemoglobin measurement, and the dishemoglobin measurement.

16. The patient monitoring method of claim 9 , further comprising displaying the output fractional oxygen saturation measurement on a display.
