Sleep Apnea Clinical Trial
Official title:
Early Sleep Apnea Termination Using Sound Stimulation
Current evidence suggest that sleep apnea-associated oxygen desaturations may induce cardiovascular morbidities in the long term, whereas arousals associated with sleep apneas seem to induce mainly transient nocturnal hypertension. Reducing the occurrence and the magnitude of sleep apnea-associated oxygen desaturations could therefore have a beneficial effect on sleep apnea-associated comobidities. Since sleep apneas usually end with an arousal allowing pharyngeal muscles reactivation, a treatment option could consist of generating an early short awakening to anticipate apnea termination and decrease the risk of oxygen desaturation. The aim of this study is thus to determine if an early sleep apnea termination through the emission of a sound can achieve lower oxygen desaturations compared with "untreated" sleep apneas.
The aim of the study is to determine the effect of short sound stimulations on sleep apnea associated desaturations 20 OSA subjects will be recruited and studied with polysomnography and a head band allowing to emit short sound stimulations during sleep. the study will take nplace at the Center for investigation and research in sleep (CIRS) The magnitude of oxygen desaturations following apnea with and without sound stimulations will be compared. The effects of different types of sound stimulations on the magnitude of cortical and autonomic reactions will also be studied as well as the patients' subjective perception of the sounds. ;
