Bioburden and Usability Evaluation of a Nasal Prototype CPAP Mask

ResMed42 enrolled

Overview

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.

Outcomes

Primary Outcomes

Changes from baseline in Bioburden and Impedance of the prototype mask components at 6 weeks

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.

Time frame: 6 weeks

Secondary Outcomes

Usability ratings of the prototype mask using a visual analog scale, compared to a reference level and the participant's current mask

Participants will be asked to complete a short questionnaire at the end of each week to evaluate the general usability of the mask system. The questionnaire will include questions related to mask comfort. The participants will answer the questions using an 11-point Likert scale.

Time frame: 6 weeks
