Ambulatory CPAP Titration in Moderate Obstructive Sleep Apnea (ATMOS)
The aim of this trial is to compare two different ways of CPAP titration:
CAP titration with fixed pressure vs. auto-titrating CPAP.

EXPERIMENTAL: Fixed CPAP titration at home
Patients will start CPAP treatment with a pressure that is calculated by the following formula (predicted pressure = (0.13 x BMI) + (0.16x neck circumference in cm) + (0.04 x AHI)) with a maximal pressure of 10 cmH2O. After 3 nights and after 7 nights, CPAP data will be remotely evaluated and pressure will be adapted based on the following rules:
|
Fixed CPAP or APAP titration at home
|
ACTIVE_COMPARATOR: APAP titration at home
Patients will start CPAP treatment with an auto-adjusting CPAP device with pressure levels between 4 and 12 cmH2O.
After 7 nights of titration, the optimal pressure will be determined by analyzing the median of the nightly pressure that included 95% of the periods (percentile 95).
CPAP treatment will be continued with this fixed optimal pressure.
