Detection and Monitoring of Stress Events During Sleep
First Claim
Patent Images
1. A computer-implemented method for monitoring a patient, comprising:
- receiving a signal associated with respiration of the patient during sleep;
processing the signal to detect a pattern of periodic breathing;
extracting from the signal a shape characteristic of the pattern; and
classifying an etiology of the periodic breathing responsively to the shape characteristic.

Abstract
A computer-implemented method for monitoring a patient (22) includes receiving physiological signals from the patient during sleep and processing at least one of the signals to detect a spontaneous stress event. One or more of the signals following the stress event are analyzed so as to evaluate a stress response of the patient.
