Sleep Quality Evolution: Dreem Under CPAP

Obstructive Sleep Apnea Clinical Trial

Official title: Evolution of Sleep Quality During the Initiation of Continuous Positive Airway Pressure Treatment in Obstructive Sleep Apnea Syndrome: An Exploratory Study

Status Recruiting

Clinical Trial Summary

Continuous positive airway pressure (CPAP) has a caricatural effect in reducing nocturnal respiratory abnormalities and improving the micro-and macrostructure of sleep. Studies characterizing the improvement of acute sleep parameters after the initiation of CPAP are limited to one or two nights of polysomnographic recording. This is related to the cost of performing these studies with repeated recordings in the laboratory and to the acceptability by patients to perform multiple nights of recordings.

Investigators currently have powerful and reliable methods allowing us to carry out nights at home in the patient's ecosystem, in real-life conditions. The characterization of sleep parameters by these methods is equivalent to a polysomnographic recording.

These technological innovations will allow us to characterize sleep before the initiation of CPAP treatment during several nights performed at home. Investigators will then be able to characterize the kinetics and stability of the improvement of sleep parameters in patients with obstructive sleep apnea syndrome in whom continuous positive airway pressure is initiated.

These data will be original and will serve as exploratory data to judge whether the objective improvement of sleep parameters in the first weeks of treatment is associated with improvement in sleepiness, quality of life, and compliance with treatment.

Clinical Trial Description

This study aims to evaluate the quality of sleep, principally the deep slow-wave sleep (sleep stage N3) before and after the initiation of continuous positive airway pressure (CPAP) treatment.

70 newly diagnosed patients with OSA requiring CPAP treatment, will be included.

For the study, they will wear the Dreem 3 headband and pulse oximeter at home before initiation of CPAP (for 7 nights) and during the first month of CPAP (for a minimum of 9 nights). They will be also equipped with a glucose sensor and a pedometer during the entire study period before and after CPAP treatment.

Patients will also complete questionnaires about their health status before CPAP treatment (at inclusion) and after one month of treatment

These devices will allow the measurements of different parameters: sleep stages, total sleep time, sleep measures derived from sleep stages, snoring, breathing rate, heart rate head movements, arterial hemoglobin oxygen saturation, pulse rate, continuous subcutaneous glucose level, and physical activity data (average daily steps, average distance walked per day).

This will generate interesting data on the sleep parameters and their evolution during the initiation of the CPAP treatment. ;
