Hemoglobin display and patient treatment
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.
1. 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;
compare the trend with an expected limit of hemoglobin; and
control the fluid delivery system based on the determined trend and the comparison.
2. The transfusion system of claim 1 , wherein the trend is determined based on a frequency transformation of the plurality of total hemoglobin measurements over the first time period.
3. The transfusion system of claim 1 , wherein the physiological monitor comprises the one or more hardware processors.
4. The transfusion system of claim 1 , wherein the fluid delivery system comprises a tube, a fluid bag, and a needle configured for insertion into the patient.
5. The transfusion system of claim 4 , wherein the tube is directly connected to the physiological monitor.
6. The transfusion system of claim 4 , wherein the controlling of the fluid delivery system comprises controlling a rate or amount of fluid administered to the patient from the fluid bag.
7. The transfusion system of claim 1 , wherein the one or more hardware processors are further configured to stop fluid delivery from the fluid delivery system based on the comparison.
8. 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;
comparing the trend with an expected limit of hemoglobin; and
controlling a fluid delivery system based on the determined trend and the comparison.
9. The electronic transfusion method of claim 8 , wherein the trend is determined based on a frequency transformation of the plurality of total hemoglobin measurements over the first time period.
10. The electronic transfusion method of claim 8 , wherein the electronic transfusion method is executed by the one or more hardware processors of a physiological monitor.
11. The electronic transfusion method of claim 8 , wherein the fluid delivery system comprises a tube, a fluid bad, and a needle configured for insertion into the patient.
12. The electronic transfusion method of claim 11 , wherein the tube is directly connected to a physiological monitor.
13. The electronic transfusion method of claim 11 , wherein the controlling of the fluid delivery system comprises controlling a rate or amount of fluid administered to the patient from the fluid bag.
14. The electronic transfusion method of claim 8 , wherein further comprising stopping fluid delivery from the fluid delivery system based on the comparison.
