Abstract

The present disclosure describes embodiments of a patient monitoring system and methods that include the measure and display of hemoglobin statistics. In an embodiment, total hemoglobin trending is displayed over a period of time. Statistics can include frequency domain analysis, which may be unique for each patient monitored. The total hemoglobin trending and/or statistics can further be used to help control the treatment of a patient, such as being used to control IV administration.

Claims

1. A patient monitoring system comprising:

a noninvasive sensor for emitting energy into a patient measurement site and detecting the energy attenuated by the patient measurement site;

a memory buffer; and

a processing unit which determines a first plurality of total hemoglobin readings over a first time period using the attenuated energy detected by the sensor and store the first plurality of total hemoglobin readings in the memory buffer,

said processing unit includes a frequency transform module which performs a frequency transform on the first plurality of total hemoglobin readings stored in the memory buffer to determine frequency data from the first plurality of total hemoglobin readings.

2. The patient monitoring system of claim 1, further comprising:

an interface to a treatment unit, wherein the interface is configured to automatically regulate the operation of the treatment unit based at least in part on the frequency data from the first plurality of total hemoglobin readings.

3. The patient monitoring system of claim 2, wherein the interface is configured to send the frequency data from the first plurality of total hemoglobin readings to the treatment unit to regulate the operation of the treatment unit.

4. The patient monitoring system of claim 3, wherein the treatment unit comprises a dialysis machine.

5. The patient monitoring system of claim 2, wherein the processing unit, in response to regulating the operation of treatment unit, determines a second plurality of total hemoglobin readings over a second time period using the attenuated energy detected by the sensor and store the second plurality of total hemoglobin readings in the memory buffer.

6. The patient monitoring system of claim 2, wherein the treatment unit comprises an IV fluid bag.

7. The patient monitoring system of claim 2, wherein the treatment unit includes administration of at least one from the following:

a drug;

blood;

plasma;

nutrition;

or

an IV fluid.

8. The patient monitoring system of claim 1, further comprising a display unit configured to display frequency data.

9. The patient monitoring system of claim 1, wherein the first time period incorporates at least a complete cycle of the patient'"'"'s total hemoglobin readings.

10. The patient monitoring system of claim 1, wherein the frequency transform module comprises an integrated circuit.

11. A patient monitor device comprising:

a processing unit which accepts signals indicative of optical energy attenuated by patient tissue detected from a noninvasive, optical sensor and further interprets the signals;

the processing unit further determines a first plurality of total hemoglobin readings; and

the processing unit includes a frequency transform module which performs a frequency transform on the first plurality of total hemoglobin readings to determine frequency analysis of the first plurality of total hemoglobin readings.

12. The patient monitor of claim 11, further comprising:

an interface to a treatment unit, wherein the interface is configured to automatically regulate the operation of the treatment unit based at least in part on the frequency analysis of the first plurality of total hemoglobin readings.

13. The patient monitor of claim 12, wherein the interface is configured to send the frequency analysis of the first plurality of total hemoglobin readings to the treatment unit to regulate the operation of the treatment unit.

14. The patient monitor of claim 12, wherein the processing unit, in response to regulating the operation of treatment unit, determines a second plurality of total hemoglobin readings.

15. The patient monitor of claim 12, wherein the treatment unit includes administration of at least one from the following:

a drug;

blood;

plasma;

nutrition;

or

an IV fluid.

16. A method for monitoring patient hemoglobin levels, the method comprising:

emitting energy into a patient measurement site for attenuation by the measurement site;

detecting attenuated energy from the measurement site;

determining a first plurality of total hemoglobin readings from the detected attenuated energy over a period of time; and

determining a first frequency signature of the first plurality of total hemoglobin readings by applying a frequency domain analysis to the first plurality of total hemoglobin readings.

17. The method of claim 16, further comprising automatically regulating the operation of the treatment unit based at least in part on the first frequency signature of the first plurality of total hemoglobin readings.

18. The method of claim 17, further comprising sending the first frequency signature of the first plurality of total hemoglobin readings to the treatment unit.

19. The method of claim 17, further comprising determining a second plurality of total hemoglobin readings and determining a second frequency signature of the second plurality of total hemoglobin readings by applying a frequency domain analysis to the second plurality of total hemoglobin readings.

20. The method of claim 19, further comprising comparing the first and second frequency signatures.
