HEMOGLOBIN DISPLAY AND PATIENT TREATMENT
First Claim
Patent Images
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 memory buffer; and
a processing unit which determines a first plurality of total hemoglobin readings over a first time period using the attenuated energy detected by the sensor and store the first plurality of total hemoglobin readings in the memory buffer,said processing unit includes a frequency transform module which performs a frequency transform on the first plurality of total hemoglobin readings stored in the memory buffer to determine frequency data from the first plurality of total hemoglobin readings.

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.
