Abstract

Conclusion: Watch-PAT may provide an accurate and clinically effective portable monitoring method for the diagnosis of obstructive sleep apnea (OSA). Objective: This study was designed to assess the accuracy and clinical efficacy of a wrist-worn portable device (Watch-PAT 100) to diagnose OSA. Methods: Twenty-seven participants with suspected OSA underwent full polysomnography (PSG). Finally, 25 subjects successfully underwent portable monitoring using Watch-PAT after full PSG. The study population consisted of 21 males and 4 females, mean age 40.9 ± 11.2 years (range 2159). Mean body mass index (BMI) was 26.2 ± 2.6 kg/m2 (range 21.232.3). All PSG were manually scored according to the new scoring manual of the American Academy of Sleep Medicine (2007) and the Watch-PAT data were analyzed by the automatic algorithm. Results: There was a high correlation of apnea-hypopnea index (AHI) (r 0.94, p <0.001) and lowest oxygen saturation (LSAT) (r 0.90, p <0.001) between the PSG and the Watch-PAT. A good agreement was also found between PSG AHI, PSG LSAT and PAT AHI, PAT LSAT, respectively. There was a significantly high concordance of the severity of AHI (Kendall tau-b 0.897, p <0.001) between the PSG and the Watch-PAT.
