<P>PROBLEM TO BE SOLVED: To provide a method and apparatus for diagnosing Cheyne-Stokes breathing from flow readings or oximeter readings by use of appropriate software in conjunction with a small hand-held device for use in a home setting. <P>SOLUTION: A signal representative of a patient's respiration is split into equal length epochs. A primary feature is extracted from each epoch that acts as a compressed representation of the signal events. Statistics are applied to the primary feature to produce one or more secondary features that represent the entire epoch. Each secondary feature is grouped with one or more other features that are extracted from the entire epoch rather than selected epoch events. This grouping is the epoch pattern. The pattern is manipulated with suitable classifier algorithm to produce a probability for each class within the algorithm, that the signal may be representative of a disease state (Cheyne-Stokes, OSA or the like). <P>COPYRIGHT: (C)2012,JPO&INPIT |
