RESPIRATION MONITORING METHOD AND SYSTEM
First Claim
1. A method of determining a respiration rate from a signal representative of a recorded respiration episode, the method comprising providing a starter pointer and an end pointer to point to a start position and an end position of the signal representative of the episode, updating the start and end pointers to identify the start and end positions of two or more uncorrupted segments within said signal, the uncorrupted segments being separated by corrupted segments, identifying the longest of the uncorrupted segments or the segment with a lowest average absolute deviation (AAD) between respiration peaks or troughs, and determining a respiration rate from the longest uncorrupted segment or the segment with the lowest AAD.

Abstract
A method of determining a respiration rate from a signal representative of a recorded respiration episode comprises identifying two or more uncorrupted segments within the signal, the uncorrupted segments being separated by corrupted segments, identifying the longest of the uncorrupted segments or the segment with a lowest average absolute deviation (AAD) between respiration peaks or troughs, and determining a respiration rate from the longest uncorrupted segment or the segment with the lowest AAD.

17. A respiration monitoring system for monitoring respiration to determine a respiration rate from a signal representative of a recorded respiration episode, the system comprising:
-
a sensor for generating a signal representative of a recorded respiration episode; and a processor configured for; providing a starter pointer and an end pointer to point to a start position and an end position of the signal representative of a recorded respiration episode, updating the start and end pointers to identify the start and end positions of two or more uncorrupted segments within said signal, the uncorrupted segments being separated by corrupted segments, identifying the longest of the uncorrupted segments or the segment with a lowest average absolute deviation (AAD) between respiration peaks or troughs, and determining a respiration rate from the longest uncorrupted segment or the segment with the lowest AAD. - View Dependent Claims (18, 19, 20)
