  Purpose

The purpose of this study is to investigate the following topics:

  • Determine the accuracy of ApneaLink Plus in separating Apneas into Obstructive Apneas, Mixed Apneas and Central Apneas.
  • Determine the accuracy of ApneaLink Plus in scoring Hypopneas according to the 2008 guidelines of the AASM = American Academy of Sleep Medcine.
  • Determine whether patients can start and stop the recorder and are able to attach the additional effort sensor by themselves using the patient instruction sheet
