Benefits
What are the benefits versus a Level 1 sleep study?
• No wait time for a sleep study in a lab
• Done from the comfort of your own bed, not a sleep lab
• No travel or time off from work required
• Private—sleep without a Registered Polysomnographic Technologist (RPSGT) watching
Who is it right for?
Who should have a Level 2 sleep study?
• Those who suffer from poor sleep but are not at risk for sleep apnea, or
• Those who are unsure of the cause of their poor sleep, or
• Those who are uncomfortable with sleeping in a lab environment and/or under observation of a
RPSGT
