Whitsundays (Nasal) Singapore External Clinical Study 1 Protocol

Each Whitsunday mask or AirFit N30i Quiet mask is worn for 7 nights. The overall purpose of this study is to evaluate the performance of the Whitsundays nasal mask system (a prototype mask) compared to the ResMed AirFit N30i Quiet mask system (a benchmark mask) in relation to seal, comfort, usability, overall performance, and efficacy.

This is a randomized, open label, cross over study to evaluate the Whitsundays nasal mask system (prototype mask) against a released mask system, the ResMed AirFit N30i Quiet mask system. The Whitsundays nasal mask system will be compared with a released mask, ResMed's AirFit N30i Quiet, as it is also a nasal mask and the most appropriate benchmark. Study participants are experienced with CPAP masks and devices and therefore will use their experience to identify areas for potential improvement. Recruitment will be done via phone calls/ SMS messages/ emails \<TBC with PI\>. Participants will be explained the details of the trial and those who wish to take part will be invited to a selected site for the first study visit. Visit 1: Participants will provide written informed consent. Participants will be shown the mask systems and trial them for fit and comfort. Participants may be asked initial questions on their first thoughts on the mask systems. If the participant and assessor are happy to proceed, the participants will use the mask and loan CPAP for trial. Visit 2: After trialing the mask systems, participants will be asked to complete a questionnaire regarding the seal and comfort of the mask system(s). Participants will then take the second mask system home to test. Visit 3: The participant will return the masks and CPAP device to the assessor. The participants' questionnaire responses will be reviewed. This concludes the participation in the study.
