Summary
Brief summary
This study is designed to determine the effectiveness of two different CPAP devices. One a standard CPAP which has the ability to store comprehensive compliance and efficacy data and the second a auto adjusting CPAP which uses the energy spectrum analysis of flow signals to automatically adjust CPAP pressure and improve sleep variables.
