What's the big difference between home sleep testing and in lab testing?

Posted 5/9/2015

Use of home sleep testing (HST) is increasing, and many predict that it may eventually become the primary testing modality over in-laboratory polysomnography (PSG). Thus, a critical question must be asked: “Does the evidence support the use of home sleep testing?” Early studies focused on validating portable monitoring (PM) technology in regard to accuracy of diagnosing obstructive sleep apnea (OSA) and identifying severity. Auto-titrating CPAP (APAP) technology has likewise been validated as an effective titration method and also as a primary treatment modality.1,2 Recent research in home sleep testing has evolved into trying to answer questions relevant to delivery of care. These questions include: 1) How should HST be applied in clinical practice, and are the clinical outcomes similar compared to PSG? 2) Is HST truly more cost efficient than in-lab PSG? Recent articles by Kuna et al, Rosen et al, Masa et al, and Pietzsch et al attempt to answer these questions and further establish under what conditions use of HST is appropriate. - See more at: http://www.sleepreviewmag.com/2013/02/home-sleep-testing-versus-in-lab-polysomnography/#sthash.YO4AaXkl.dpuf
