In this study the investigators will analyze the influence of smoking, benzodizepine use, and obesity among patients with severe Obstructive Sleep Apnea (sOSA).
This study is a retrospective study. Patients enrolled: all patients with a PSG (polysomnography) between 1st January 2014 and 30th June 2015.
First analysis: influence of smoking, benzodiazepine use, and obesity on the AHI (Apnea Hypopnea Index: the number of apnea and hypopnea per hour of sleep).
Second analysis: only among patients with sOSA: influence of smoking, benzodiazepine use, and obesity on sleep fragmentation and night oximetry.
