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.

PAP therapy supplies pressurized air from the flow generator to the upper airway via air tubing and a mask to prevent the repetitive collapse of the upper airway during sleep.
Subjective usability
Comparison of the seal, comfort, usability and overall preference of the Whitsundays nasal mask system to the AirFit N30i Quiet mask system and/or Criterion Score of 6
Time frame: 6 weeks
Apnea Hypopnea Index (Events/hour)
Objective AHI taken from the participant's CPAP device used during the trial, with a comparison of the Whitsundays nasal mask to the benchmark AirFit N30i Quiet mask or clinically relevant data. nasal mask system to the AirFit N30i Quiet mask system and/or Criterion Score of 6
Time frame: 6 weeks
General Usability
General subjective usability scores from participant. Each usability items of the Whitsundays Nasal Mask System and AirFit N30i Quiet Mask System will be rated on a Likert Scare questionnaire. A score of 10 is considered very favourable whereas score of 0 is considered very unfavourable.
Time frame: 6 weeks
Leak (L/minute)
Calculated leak from the CPAP device provides information on how well the Whitsundays Nasal Mask and AirFit N30i Quiet Mask fit on the patient.
Time frame: 6 weeks
CPAP Pressure (cmH2O)
Calculated average pressure from the CPAP device, which indicates how much pressure patients need to keep the airway open.
Time frame: 6 weeks
Usage Hours (hours/night)
Average usage hours taken from the participants' CPAP device used during the study.
Time frame: 6 weeks
