1. A method of diagnosis, comprising:
- receiving a signal associated with respiration of a patient;
processing the signal so as to identify features that are indicative of beginning and end times of apnea episodes;
computing time shifts between recurrences of the features;
processing the time shifts so as to generate an output comprising a plurality of bands corresponding to different multiples of a cycle length of the apnea episodes.

Abstract
A method for diagnosis comprises receiving a signal associated with respiration of a patient. The signal is processed so as to identify features that are indicative of beginning and end times of apnea episodes. Time shifts between recurrences of the features are computed and processed so as to generate an output comprising a plurality of bands corresponding to different multiples of a cycle length of the apnea episodes.

14. Apparatus for diagnosis, comprising:
-
a sensor, which is configured to be coupled to a body of a patient and to output a signal associated with associated with respiration of the patient; and a processor, which is coupled to process the signal so as to identify features that are indicative of beginning and end times of apnea episodes, to compute time shifts between recurrences of the features, and to process the time shifts so as to generate an output comprising a plurality of bands corresponding to different multiples of a cycle length of the apnea episodes. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A computer software product, comprising a computer-readable medium in which program instructions are stored, which instructions, when read by a computer, cause the computer to receive a signal associated with respiration of a patient, to process the signal so as to identify features that are indicative of beginning and end times of apnea episodes, to compute time shifts between recurrences of the features, and to process the time shifts so as to generate an output comprising a plurality of bands corresponding to different multiples of a cycle length of the apnea episodes.
