About this trial
This is an interventional treatment trial for Obstructive Sleep Apnea Syndrome
Eligibility Criteria
Inclusion Criteria: Patients with proven Obstructive Sleep Apnea Syndrome Apnea-hypopnea-index > 20/h Awaking index > 30/h Exclusion Criteria: Severe nasal obstruction Hypoventilation Excessive sleep fragmentation caused by non-respiratory factors COPD (FEV1/FVC < 65%) CPAP compliance < 3h per night Insufficient sleep time (< 2h TST) during one of both parts of the split night CPAP-titration Patients needing > 16 mbar CPAP pressures

- University Hospital Ghent
Outcomes
Primary Outcome Measures
Respiratory control expressed by residual number of obstructive and central apneas, hypopneas and snoring
Arousal index
Pressure profile Auto-CPAP (P50, P95 en Pmax)
All outcomes are measured during polysomnography
Secondary Outcome Measures
Pressure adaptation during polysomnography according to body position and sleep stage, pressure variability
Measurements of comfort, subjective evaluation by the patient by questionnaires immediately after polysomnography

5. Study Description
Brief Summary
Comparison of automatic CPAP with fixed CPAP in patients with OSAS
Detailed Description
The polysomnography is divided into two parts, randomly assigned:
in one part, the patient uses the automatic CPAP device in titration mode
in the other part, the patient uses the CPAP device, in fixed mode according to the prediction formula
