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 patient monitoring system comprising:
a light emitter configured to emit energy into a tissue site of a patient;
a detector configured to detect a response from the tissue site responsive to the emission of energy into the tissue site of the patient; and
one or more hardware processors configured to:
determine a plurality of hemoglobin concentration measurements over time for the tissue site based on the detected response;
perform a frequency transform on the plurality of hemoglobin concentration measurements; and
display a plurality of frequency components on a display screen of a patient monitor based on the performed frequency transform of the plurality of hemoglobin concentration measurements.
2. The patient monitoring system of claim 1 , wherein the one or more hardware processors are further configured to determine an oxygen saturation of blood flow into the tissue site based on the detected response.
3. The patient monitoring system of claim 2 , wherein the oxygen saturation is displayed on the display screen.
4. The patient monitoring system of claim 1 , wherein the one or more hardware processors are further configured to determine a trend in total hemoglobin based on the frequency transform.
5. The patient monitoring system of claim 4 , wherein the one or more hardware processors are further configured to provide an indication of the trend to a dialysis management system.
6. The patient monitoring system of claim 4 , wherein the one or more hardware processors are further configured to provide an indication of the trend to an infusion management system.
7. The patient monitoring system of claim 4 , wherein the one or more hardware processors are further configured to determine hemoglobin abnormalities based on the trend in total hemoglobin.
