Title: SYSTEM FOR DETERMINING A SET OF AT LEAST ONE CARDIO-RESPIRATORY DESCRIPTOR OF AN INDIVIDUAL DURING SLEEP
Abstract:
The invention relates to a method for detecting a set of events that are potentially indicative of sleep disturbances. The method is essentially characterized by: - Recording (100) beforehand in a data memory o A first accelerometer in a thoracic position, o A second accelerometer, synchronized with the first, in an abdominal position; o A photoplethysmography sensor in a thoracic position; - Filtering (110) said data by extraction o of low-frequency, medium-frequency and high-frequency ranges of the first accelerometer, and o at least one low-frequency range of the second accelerometer, - Determining (120), in at least one range, a set of characteristics that are representative of a cardio-respiratory state, and also their moment of extraction, and - Comparing (130) said set of characteristics with a reference model comprising a correlation between a set of characteristics distributed over time and a set of physiological events, and - Deducing therefrom (140) a set of at least one probable corresponding event that the individual has faced.
