Clinical Trial Summary

The aim of this trial is to compare two different ways of CPAP titration:

CAP titration with fixed pressure vs. auto-titrating CPAP.

Description:

Continuous positive airway pressure (CPAP) for the treatment of moderate obstructive sleep apnea (OSA) is only reimbursed in Belgium after in-laboratory overnight titration. Nevertheless, in a recent clinical practice guideline of the AASM, it is recommended that PAP therapy can be initiated using either in-laboratory titration or auto-titrating CPAP (APAP) at home in OSA patients without significant comorbidities. Indeed, several studies evaluated the impact of titration with APAP at home in these patients and showed that the outcome is comparable with in-hospital titration. Up to now, evidence for home titration with fixed CPAP (and follow-up via telemonitoring) is very limited. The use of sleep laboratory space is costly and limits access for diagnostic studies. This study aims to evaluate whether CPAP titration at home with fixed CPAP produces outcomes equal to those following APAP titration.
