An Exploratory Investigation of the Use of Drive App to Measure Sleep Parameters in Users of CPAP Therapy

The purpose of this study is to evaluate the usability and suitability of the Drive app (app under test) to measure sleep parameters during CPAP use. This is a prospective, non-randomized, single arm exploratory study without blinding. Current users of CPAP therapy will be recruited for this study and will be provided with a smartphone (app under test installed) and a non-contact motion sensor in their home environment. These devices will measure sleep metrics such as sleep stages and breathing metrics that may be associated with sleep disordered breathing. Usage and setup instructions will be provided for the study. Participants will contribute up to 7 overnight recordings in the home environment and will complete daily questionnaires detailing their experience. The study may be completed in two distinct phases, with an analysis performed after each phase. Each phase is expected to last up to six weeks with the overall study duration taking up to 12 months.
