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 of a patient and detecting the energy attenuated by the patient measurement site;
- a memory buffer;
- and
- a hardware processor configured to determine 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,
- wherein said hardware processor is further configured to frequency transform the first plurality of total hemoglobin readings stored in the memory buffer,
- determine frequency data from the first plurality of total hemoglobin readings;
- and
- determine a hemoglobin characteristic of the patient from the frequency data.
A patient monitoring system comprising:
- a hardware processor configured to:
- determine a first plurality of total hemoglobin readings over a first time period using the attenuated energy detected by a noninvasive sensor attached to a patient;
- store the first plurality of total hemoglobin readings in a memory buffer;
- transform the first plurality of total hemoglobin readings stored in the memory buffer in a frequency domain;
- and
- determine a hemoglobin characteristic of the patient based on the transformed total hemoglobin readings.
