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 receive a calculated value indicative of a physiological rate. Based on the value, the system may select pairs of values of the physiological signal that are particularly spaced. The system may determine a state for each pair of values. The state may correspond to a set of criteria such as, for example, equalities, inequalities, logical operators, or other criteria. The system may determine a number of state transitions based on the determined states, and qualify or disqualify the calculated value based on the number of state transitions.
First claim
Opening claim text (preview).
What is claimed is: 1. A subject monitoring pulse oximetry system for processing physiological information of a subject, comprising: a pulse oximetry sensor configured to generate a physiological signal, wherein the sensor detects light attenuated by the subject; and a pulse oximeter coupled to the sensor, wherein the pulse oximeter is configured to: receive a calculated value that is a candidate for being indicative of a physiological rate of the subject; select a plurality…
