Assessment method [1]

0
The population of microorganisms on mask components will be measured after 6 weeks of continuous use by a participant on their PAP therapy device to assess the safe replacement interval of the component. The impedance of the mask will also be measured to assess whether the build up of microorganisms on the mask component will affect the usability and effectiveness of the mask. Bioburden and impedance testing will be conducted in a lab environment on return of the prototype mask and components.

Summary
Brief summary
AIM AND HYPOTHESIS: The purpose of this study is to monitor the bioburden and impedance characteristics of a prototype mask system and to evaluate the usability of the mask system. The mask system will be assessed according to objective data recordings and user questionnaires. It is hypothesised that the prototype mask components will not pose a health risk (with regards to bioburden and impedance) and that the mask system will pass usability objectives to adequately deliver CPAP treatment.
