The ApneaLink respiratory disturbance indices (RDI), PSG apnea-hypopnea indices (AHI), and PSG oxygen desaturation index (ODI) were compared. ApneaLink data were analyzed either with the automated computerized algorithm provided by the manufacturer following the American Academy of Sleep Medicine standards (default setting DFAL) or The University of British Columbia Hospital sleep laboratory standards (alternative setting, ATAL). PSG sleep and respiratory events were scored manually according to standard criteria. ![]() A simultaneous recording of both the standard in-laboratory PSG and an ambulatory level 4 sleep monitor (ApneaLink) was performed during an overnight study for each patient. This study was designed to assess the sensitivity and specificity of a portable sleep apnea recording device (ApneaLink) using standard polysomnography (PSG) as a reference and to evaluate the possibility of using the ApneaLink as a case selection technique for patients with suspected obstructive sleep apnea (OSA).įifty patients (mean age 48.7 +/- 12.6 years, 32 males) were recruited during a 4-week period.
