1. A patient monitoring system comprising:
- a noninvasive sensor for emitting energy into a patient measurement site and detecting the energy attenuated by the patient measurement site;
a processing board comprising;
an instrument manager including a memory buffer; and
a FFT module in communication with the instrument manager;
wherein the instrument manager is adapted to determine at least a plurality of total hemoglobin readings over time using the attenuated energy detected by the sensor and to store the plurality of total hemoglobin readings in the memory buffer; and
wherein the FFT module analyzes the plurality of total hemoglobin readings stored in the memory buffer; and
a display adapted to output at least one of said plurality of total hemoglobin readings or said FFT module analysis.

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.
