Proc Am Thorac Soc 5:144–153Īurora RN, Casey KR, Kristo D et al (2010) Practice parameters for the surgical modifications of the upper airway for obstructive sleep apnea in adults. Both sleep efficiency and the arousal index affect the results of ALP.Įckert DJ, Malhotra A (2008) Pathophysiology of adult obstructive sleep apnea. ALP detects central sleep apnea to a certain degree.

Manual scoring is recommended however, Auto AASM is also acceptable. ConclusionĪLP is an accurate and reliable device for the diagnosis of OSA. Moderate agreement between PSG and ALP based on central apnea index was observed. The degree of agreement between PSG and ALP was affected by sleep efficiency and the arousal index.

Regarding agreement with PSG, the manual scoring system was most superior, followed by the Auto AASM, and Auto scoring systems. The area under curve was highest for the manual scoring system and lowest for the auto scoring system, and increased as the apnea-hypopnea index (AHI) cutoff value increased from 5 to 30. Sensitivity was good for all three scoring systems, while specificity was poor for the Auto scoring system. ResultĪmong the 200 patients who were recommended for enrollment, 149 completed the study. The parameters of ALP were scored based on three different systems, Manual, Auto AASM, and Auto scoring systems.

If consent was obtained, patients underwent standard polysomnography (PSG) and ALP evaluation simultaneously at the hospital (ALP lab), and repeated ALP at home (ALP home) within 1 month. We recommended enrolling of 200 consecutive patients who had been referred because of habitual snoring or witnessed apnea during sleep. The aim of this study is to evaluate the validation of ApneaLink™ Plus (ALP) based on a large number of subjects in a prospective design.
