Evaluation of a single-channel portable monitor for the diagnosis of obstructive sleep apnea.

ABSTRACT:

Study objective

To validate the ApneaLINK (AL) as an accurate tool for determining the presence of obstructive sleep apnea (OSA) in an at-risk sleep clinic population in a home test environment.

Methods

Consecutive participants referred with the suspicion of OSA were evaluated in the home with the AL portable monitor (AL Home), followed by simultaneous data collection with diagnostic polysomnography (PSG) and AL in the sleep laboratory (AL Lab). Prevalence, sensitivity, specificity, and ROC curves were calculated for PSG vs. AL Lab, PSG vs. AL Home, and AL Lab vs. AL Home test. Pearson correlations and Bland-Altman plots were constructed.

Results

Fifty-three (55% female) participants completed the entire study. The mean age of the population was 45.1 ± 11.3 years, and
