Question

  1. What is the comparative validity and diagnostic accuracy of portable testing devices that use three channels versus devices that use four channels for the diagnosis of sleep apnea?
  2. What is the validity and diagnostic accuracy of any combination of oxygenation, nasal pressure, heart rate, pulmonary effort, or body position as measured by portable three channel or four channel testing devices for the diagnosis of sleep apnea?
  3. What are the evidence-based guidelines regarding the appropriate channels and appropriate number of channels for the diagnosis of sleep apnea?

Key Message

One evidence-based guideline was identified regarding the appropriate channels and appropriate number of channels for the diagnosis of sleep apnea. No literature was identified regarding the validity and diagnostic accuracy of portable testing devices that use three channels versus four channels for the diagnosis of sleep apnea.
