Patent Images
1. A method for detecting disordered breathing implemented at least in part within a patient, comprising:
- detecting a respiration pattern of a plurality of respiration cycles;
determining breath intervals (BI) and tidal volume (TVOL) measurements of each of the respiration cycles;
producing an unevenly sampled instantaneous minute ventilation (iMV) signal using the BI and TVOL measurements;
producing an evenly sampled iMV signal (resampled iMV signal) using the unevenly sampled iMV signal; and
detecting disordered breathing based on a comparison between a baseline threshold and the resampled iMV signal.

Abstract
A respiration pattern of a number of respiration cycles is detected and breath intervals (BI) and tidal volume (TVOL) measurements of each of the respiration cycles are respectively determined. An unevenly sampled instantaneous minute ventilation (iMV) signal is produced using the BI and TVOL measurements, and an evenly sampled iMV signal (resampled iMV signal) is produced using the unevenly sampled iMV signal. Disordered breathing is detected based on a comparison between a baseline threshold and the resampled iMV signal.
