To diagnose sleep disorders, practitioners primarily use polysomnography (PSG), a precise but costly, cumbersome method that is limited to a single observation. This does not allow for longitudinal monitoring of sleep habits in real-world conditions. An alternative is offered with the C. Santé software receiving information from sensors installed on medical bed. This software analyzes cardiorespiratory parameters and sleep phases without disturbing the patient, enabling continuous and comfortable monitoring. A preliminary study aims to validate the reliability of the C. Santé software analysis, by comparing it to the PSG analysis, considered the gold standard.
