Abstract
Official abstract text for this publication.
A physiological monitoring system may determine physiological information, such as physiological rate information, from a physiological signal. The system may generate a difference signal based on the physiological signal and sort the difference signal to generate a sorted difference signal. The system may identify a midpoint of a first segment of the difference signal and a midpoint of a second segment of the difference signal. The first segment may correspond to positive values of the difference signal and the second segment may correspond to negative values of the difference signal. The system may determine an algorithm setting based on the first midpoint and the second midpoint. The algorithm setting may, for example, affect the amount of filtering applied to the physiological signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A subject monitoring pulse oximetry system for determining physiological information of a subject, comprising: a pulse oximetry sensor configured to detect light attenuated by the subject and generate a photoplethysmographic (PPG) signal based on the detected attenuated light; and a pulse oximeter coupled to the pulse oximetry sensor, wherein the pulse oximeter is configured to: store a rate algorithm; generate a difference signal based on the PPG sign…
