About

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.

23 participants in 1 patient group

Prototype mask

Experimental group

Description:

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.

Treatment:

Device: CPAP mask - prototype
