METHODS AND SYSTEMS FOR QUALIFYING CALCULATED VALUES BASED ON A STATISTICAL METRIC
First Claim
1. A subject monitoring system for processing physiological information of a subject, comprising:
- a sensor configured to generate a physiological signal, wherein the sensor detects light attenuated by the subject; and
processing equipment coupled to the sensor, wherein the processing equipment is configured to;
receive a calculated value that may be indicative of a physiological rate of the subject;
generate a plurality of value pairs each comprising a first sample point of the physiological signal and a second point of the physiological signal spaced apart by a particular spacing, wherein the particular spacing is based on the calculated value;
determine a best fit linear relationship based on the plurality of value pairs;
determining at least one statistical metric based on the linear relationship and the plurality of value pairs; and
qualify or disqualifying the calculated value based on the at least one statistical metric.

Abstract
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. The system may generate value pairs from a first collection of values of the physiological signal and another collection of corresponding value of the physiological signal spaced from the first collection based on the calculated value. The system may determine a best fit linear relationship based on the value pairs and determine at least one statistical metric based on the linear relationship and the value pairs. The system may qualify or disqualify the calculated value based on the at least one statistical metric.
