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 physiological monitor connected with a fluid delivery controller, said physiological monitor comprising:
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;
perform a frequency transform on the determined plurality of total hemoglobin measurements;
determine a physiological condition of the patient based on the frequency transformed total hemoglobin measurements; and
transmit an indication of the determined physiological condition to the fluid delivery controller.
2. The physiological monitor of claim 1 , wherein the fluid delivery controller and the physiological monitor are included in a single unit.
3. The physiological monitor of claim 1 , wherein fluid delivery controller is configured to control a rate or amount of fluid administered to the patient from the fluid bag based on the indication.
4. The physiological monitor of claim 1 , wherein transmission is through a wireless communication.
5. The transfusion system of claim 1 , wherein transmission is through a wired communication.
6. A physiological monitoring method comprising:
determine a plurality of total hemoglobin measurements over a first time period based on detected attenuated energy from a noninvasive sensor attached to a measurement site of a patient;
performing a frequency transform on the determined plurality of total hemoglobin measurements;
determining a physiological condition of the patient based on the frequency transformed total hemoglobin measurements; and
transmitting an indication of the determined physiological condition to a fluid delivery controller.
7. The physiological monitoring method of claim 6 , further comprising controlling a rate or amount of fluid administered to the patient from a fluid bag based on the indication.
8. The physiological monitoring method of claim 6 , wherein the transmission is through a wireless communication.
9. The physiological monitoring method of claim 6 , wherein the transmission is through a wired communication.
