简要总结
Continuous positive airway pressure (CPAP) continues to be the primary therapy prescribed for the treatment of obstructive sleep apnea (OSA). Although effective, adherence to CPAP is suboptimal in many patients, making alternative therapies desirable. Recently, a novel device (Provent™) has been developed for the treatment of snoring and OSA. The purpose of the current study is to examine how well the Provent™ device treats OSA with particular attention to the how the it may treat sleep apnea and who may most likely benefit from the use of this treatment.

结局指标
主要结局
Change in AHI
时间窗: Comparisons were made between the 2 nights
The primary outcome was the change in the apnea hypopnea index (AHI). Sleep apnea events are defined as apneas and hypopneas.The AHI is a measure of sleep apnea severity. An AHI \> 5 event/h is considered abnormal. AHI values are typically categorized as 5-15 events/hr = mild; 15-30 events/hr = moderate; and \> 30 events/hr = severe. For this study we compared the change in AHI from the baseline sleep study (No Provent) compared to the treatment night sleep study (on Provent).
