Sleep Apnea : Diagnosis and Monitoring

Completed
Conditions
Obstructive Sleep Apnea
Registration Number
NCT03571477
Lead Sponsor
University Hospital, Grenoble
Brief Summary

This prospective study aims to evaluate a new medical screening method to detect and discriminate sleep apnea-hypopnea events. A new device called ApneaBand will be tested to propose a new screening method facilitating the diagnosis and monitoring of the sleep apnea syndrom, still underdiagnosed. This device will be tested in comparison with polysomnography (PSG), the gold standard reference method of sleep apnea diagnosis.

Detailed Description

The objective of this study is to dertermine the performance of the ApneaBand, a new non-intrusive and portable device, in detecting sleep apnea, in comparison with PSG.

40 apneic and non apneic subjects will wear the ApneaBand recording the different sleep stages and the occurency of apnea-hypopnea sleep events through four sensors including oximetry (oxygen saturation), photoplethysmography (pulse wave), electrodermal activity and tri-axial accelerometer (movements).

Inclusion visit will be proceeded at the University Hospital Grenoble-Alpes ; polysomnography and mesures by the ApneaBand will be proceeded at the patient's home by IC@dom. Patients will be equiped with PSG + ApneaBand during the first night and with ApneaBand only the second night.
