Analysis of a New Mask for Positive Airway Pressure (PAP) Device Users
- Conditions
- Obstructive Sleep Apnea
- Interventions
- Device: CPAP mask - prototype
- Registration Number
- NCT01847846
- Lead Sponsor
- ResMed
- 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.

Group Intervention Description Prototype mask CPAP mask - prototype 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.
- Primary Outcome Measures
Name Time Method To measure and compare the prevalence of microorganisms within the new mask over a period of 8 weeks up to 8 weeks of use The mask is for single user use only. The participants will be instructed not to wash or clean the material for the duration of the study. The mask will be returned in a sealed bag and sent off for testing within 24 hrs after the trial.
- Secondary Outcome Measures
Name Time Method Measure and compare mask efficacy over a period of 8 weeks After 2, 4, 6 and 8 weeks of use The efficacy variables that will be measured and compared at each time point are:
Apnea Hypopnea Index (AHI; the number of apneas and hypopneas per hour), mask leak, number of hours of use per night, and user compliance will be measured
