Group/Cohort Intervention/treatment
Polysomnography
Patients undergo an one-night in-hospital polysomnography to diagnose sleep-disordered breathing
Other: Polysomnography
One night polysomnography performed using standard techniques and scored in accordance with American Academy of Sleep Medicine standards. Polysomnography monitors sleep by electroencephalography (F4-A1, C4-M1, O2-M1 F3-M2, C3-M2, O1-A2), electro-myography (submental and tibialis anterior muscles), electro-oculography, nasal flow, respiratory effort, pulse oximetry and transcutaneous carbon dioxide partial pressure.




Primary Outcome Measures :
  1. Apnoea-hypopnoea index [ Time Frame: 1 night on Day 1 ]
    Prevalence of sleep-disordered breathing during 1 night polysomnography measured by apnoea-hypopnoea index.


Secondary Outcome Measures :
  1. Sleep stages [ Time Frame: 1 night on Day 1 ]
    Characterize the sleep architecture during 1 night polysomnography by evaluating the time spend in various sleep stages (N1, N2, N3, REM, measured by EEG)
