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 method of controlling a treatment unit, the method comprising:

controlling one or more light emitters configured to transmit optical radiation towards a tissue site of a patient;

receiving attenuated optical radiation from the tissue site of the patient corresponding to the transmitted optical radiation;

applying pattern detection rules on the determined first plurality of hemoglobin measurements; and

transmitting a control signal to a treatment unit based on an output of the applied pattern detection rules on the determined first plurality of hemoglobin measurements.

3. The method of claim 2, wherein the pattern detection rules comprise a frequency transform.

4. The method of claim 2, wherein the pattern detection rules comprise comparing the first plurality of hemoglobin measurements with a baseline measurement.

5. The method of claim 2, wherein the pattern detection rules comprise determining a change in the first plurality of hemoglobin measurements over time.

6. The method of claim 2, wherein the control signal is configured to change an operation of a dialysis machine.

7. The method of claim 6, wherein the operation comprises:

alter processing of blood, inject drugs, turn off, and turn on.
