Plain English summary of protocol
Background and study aims
Obstructive Sleep Apnoea (OSA) is a very common condition characterised by repetitive episodes of complete or partial upper airway obstruction during sleep. Continuous positive airway pressure therapy (CPAP) is the best available treatment for OSA: it helps people breathe more easily during sleep by delivering a constant level of pressure. However CPAP is not always well tolerated and 8–15% of patients stop treatment after one night. The mask is an essential element of CPAP and mask discomfort is often the reason for stopping CPAP. Also, the choice of initial mask is critical to avoid repeated interface changes that impact on patient motivation and increase costs. There have been few studies on the influence of the choice of mask on CPAP. The aim of this study is to compare different nasal masks in patients with OSA treated by CPAP.
Who can participate?
Newly-diagnosed sleepy OSA patients.
What does the study involve?
Participants are allocated to one of two groups:
Group 1 (MFX group) receives CPAP (AutoSet, ResMed) via ResMed Mirage FX® nasal mask.
Group 2 (Control group) receives CPAP (AutoSet, ResMed) via Fisher & Paykel Zest® or HC407®; or Philips Respironics EasyLife® nasal mask.
What are the possible benefits and risks of participating?
Possible benefits are better mask comfort and CPAP therapy adherence. No additional risk.
Where is the study run from?
4 centres in France
When is the study starting and how long is it expected to run for?
March 2011 to December 2013
Who is funding the study?
ResMed (France)
Who is the main contact?

| Scientific title | Impact of different nasal masks on CPAP therapy for obstructive sleep apnea: a randomized comparative trial |
| Study objectives | Patient interface is important for the success of continuous positive airway pressure (CPAP) but few trials have examined the influence of mask choice on CPAP. This study compared the impact of different nasal masks on CPAP in patients with newly-diagnosed obstructive sleep apnea (OSA) who were randomized to receive CPAP via different first-line nasal masks. |
