The Evaluation of a New Nasal Mask for the Treatment of Obstructive Sleep Apnea

The investigation is a prospective, non-randomized, non-blinded study. Up to 45 OSA participants who currently use a nasal, sub-nasal or pillows mask will be recruited. The study will involve a baseline (Visit 1) data gathering with the participant's PAP therapy and their usual mask. This will be followed by the participants being fitted with the trial nasal mask by a mask fitting expert for use in-home (Visit 2). There will be a follow up phone call to gain feedback or address any issues after 3±1 days. The participant will then come in to return the mask (Visit 3) and give feedback on their experience using the mask in home in the form of a structured interview during Visit 3. If the participants prefer the trail nasal mask they will be asked if they would like to continue using the trial mask for a further six months in-home. There will be a follow up monthly phone call to gain feedback or address any issues during the extension. At the end of the six month extension period, the participants will return the trial nasal mask to the institution and give feedback on their experience using the mask in home in the form of a self-administered questionnaire. Participants will revert to their usual masks thereafter. Neither the participants nor the investigators will be blinded to the study.
