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. (canceled)

2. A transfusion system comprising:

a physiological monitor connected with a fluid delivery system;

a noninvasive sensor configured to emit energy into a measurement site of a patient and detect the energy attenuated by the patient measurement site; and

one or more hardware processors configured to;

determine a plurality of total hemoglobin measurements over a first time period based on the detected attenuated energy;

determine a trend in the plurality of total hemoglobin measurements over the first time period; and

control the fluid delivery system based on the determined trend.

3. The transfusion system of claim 2, wherein the trend is determined based on a frequency transformation of the plurality of total hemoglobin measurements over the first time period.

4. The transfusion system of claim 2, wherein the physiological monitor comprises the one or more hardware processors.

5. The transfusion system of claim 2, wherein the fluid delivery system comprises a tube, a fluid bad, and a needle configured for insertion into the patient.

6. The transfusion system of claim 5, wherein the tube is directly connected to the physiological monitor.

7. The transfusion system of claim 5, wherein the controlling of the fluid delivery system comprises controlling a rate or amount of fluid administered to the patient from the fluid bag.

8. The transfusion system of claim 2, wherein the one or more hardware processors is further configured to compare the trend with an expected limit and further control the fluid delivery system based on the comparison.

9. The transfusion system of claim 8, wherein the one or more hardware processors are further configured to stop fluid delivery from the fluid delivery system based on the comparison.

10. An electronic transfusion method comprising:

determining a plurality of total hemoglobin measurements over a first time period based on attenuated energy detected from a measurement site of a patient responsive to energy emitted by a noninvasive sensor into the measurement site;

determining a trend in the plurality of total hemoglobin measurements over the first time period; and

controlling a fluid delivery system based on the determined trend.

11. The electronic transfusion method of claim 10, wherein the trend is determined based on a frequency transformation of the plurality of total hemoglobin measurements over the first time period.

12. The electronic transfusion method of claim 10, wherein the electronic transfusion method is executed by the one or more hardware processors of a physiological monitor.

13. The electronic transfusion method of claim 10, wherein the fluid delivery system comprises a tube, a fluid bad, and a needle configured for insertion into the patient.

14. The electronic transfusion method of claim 13, wherein the tube is directly connected to a physiological monitor.

15. The electronic transfusion method of claim 13, wherein the controlling of the fluid delivery system comprises controlling a rate or amount of fluid administered to the patient from the fluid bag.

16. The electronic transfusion method of claim 10, further comprising comparing the trend with an expected limit and further control the fluid delivery system based on the comparison.

17. The electronic transfusion method of claim 16, wherein further comprising stopping fluid delivery from the fluid delivery system based on the comparison.
