Obstructive Sleep Apnea Hypopnoea Syndrome (OSAHS) is a common disorder characterized by partial (hypopnoea) or total (apnea) closure of the upper airways during sleep. It is associated with hypertension, stroke, car accidents, diabetes, metabolic syndrome and depression. Although this disease is related to major morbidity and mortality1, the prevalence of OSAHS is underestimated. The physiopathology of OSAHS is multifactorial and not yet fully understood. Numerous pathophysiological risk factors have been recognized: anatomical abnormalities, impaired upper airway dilators, unstable respiratory control and diminished arousal threshold.
