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.
Claims20
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.
A patient monitor device comprising:
- a processing unit which accepts signals indicative of optical energy attenuated by patient tissue detected from a noninvasive, optical sensor and further interprets the signals;
- the processing unit further determines a first plurality of total hemoglobin readings;
- and
- the processing unit includes a frequency transform module which performs a frequency transform on the first plurality of total hemoglobin readings to determine frequency analysis of the first plurality of total hemoglobin readings.
A method for monitoring patient hemoglobin levels, the method comprising:
- emitting energy into a patient measurement site for attenuation by the measurement site;
- detecting attenuated energy from the measurement site;
- determining a first plurality of total hemoglobin readings from the detected attenuated energy over a period of time;
- and
- determining a first frequency signature of the first plurality of total hemoglobin readings by applying a frequency domain analysis to the first plurality of total hemoglobin readings.
