NCT00772044

Brief Summary

Primary Endpoints:

  • Comparison of difference in AHI at one-week in-lab polysomnography between "device on" and "device off" nights, controlling for sleep position (supine vs. non-supine) Secondary Endpoints: By polysomnography, reduction in:
  • AHI with device on vs. off at 3 months, controlling for sleep position
  • Oxygen desaturation index with device on vs. off
  • Arousal index with device on vs. off
  • Duration of snoring with device on vs. off
  • Epworth Sleepiness Scale Patient acceptance, in terms of:
  • Refusal rate at screening
  • Discontinuation rate during follow-up
  • Daily compliance rate
  • Device-related adverse events
  • Serious adverse events
