Description of intervention(s) / exposure
Treatment: Devices - CPAP mask - prototype

Experimental: Prototype mask - Participants will be randomised to trial the new prototype mask for 4 and 8 weeks. The prototype mask will be used in conjunction with the participant's home CPAP machine. The participant's will be instructed to use the prototype mask every night until the completion of the trial. No changes will be made to the participant's prescribed CPAP settings.

Summary
Brief summary
BACKGROUND AND AIMS Continuous positive airway pressure (CPAP) is an effective therapy to
treat sleep apnea. Sleep apnea is a condition where the airways collapse when the patient is
asleep. CPAP treats sleep apnea by delivering an air pressure to the airways, splinting the
airways open. CPAP is a device that sits besides the bed and is applied to the patient using
a face mask.

The development of new CPAP masks is an on-going focus at ResMed Ltd in a bid to improve
comfort and user compliance. ResMed are developing a new mask and investigations are required
to evaluate mask performance over time.

ResMed Ltd design and manufacturer CPAP masks. The revision and development of masks is an
on-going focus of the company in a bid to improve usability and patient compliance while
maintaining optimum treatment. ResMed is developing a new mask. Investigations are therefore
required to determine how much matter is built-up on the mask over time and to evaluate mask
performance (including comfort and seal) and efficacy.

AIMS

The aims of the study are:

1. To measure and compare the change in the abundance of microbes on the new mask over a
period of 8 weeks

2. To measure and compare the change in comfort, seal, stability, efficacy, leak and user
compliance of this new mask over a period of 8 weeks

3. To measure and compare the change in comfort, seal, stability, efficacy, leak and user
compliance of this new mask versus an available mask

It is hypothesised that:

1. The new mask acquires microbes from the user but there is no difference in the abundance
of microorganisms between 2 and 8 weeks.

2. The new mask maintains the same degree of comfort, seal, stability, efficacy, leak and
compliance between 2 and 8 weeks.

3. Compared to the existing mask, the new mask provides a higher degree of comfort, seal
and stability and improves user compliance. The new mask also maintains efficacy, and
maintains or reduces leak compared to the current masks.
