The study will provide valuable information regarding benefits of telemonitoring in clinical work with CPAP therapy. Implementation of telemedicine-based monitoring of CPAP therapy may be an important part of increasing adherence among patients but also in the development of a more cost-effective care as it can provide clinics with increased treatment capacity and follow-up of both new and established patients. It would further improve the care for these patients who often have a lifelong treatment, which aims to reduce the risk of developing cardiovascular disease or premature death.
