Title: Evaluation of a portable sleep device in patients with obstructive sleep apnea hypopnea syndrome
Abstract: OBJECTIVE To evaluate the accuracy of the watch peripheral arterial tone(Watch-PAT) in the diagnosis of obstructive sleep apnea hypopnea syndrome(OSAHS). METHODS A total of 51 outpatients who had chief complaint of sleep snoring were carried out WatchPAT test and polysomnography(PSG) simultaneously, and the results were statistically compared. RESULTS Fifty one patients, consisted of 44 males and 7 females, had the mean age of(45.7±12.0) years( ±s) and the mean body mass index of(28.8±3.6) kg/m2.The mean PSG apnea hypopnea index(AHI) was(45.69±12.02) events per hour, and mean Watch-PAT AHI was(35.49±24.49) events per hour. Significant correlation has been detected between Watch-PAT AHI and PSG AHI(r =0.878, P 0.001). The sensitivit y and specif icit y of Watch-PAT were 97.73% and 85.71%, when PSG-AHI≥5/ h events per hour was setting as the threshold value to diagnose OSAHS. The diagnostic eff iciency of Watch-PAT has been tested by ROC curve, and the area under the curve approached to 0.997. CONCLUSION The Watch-PAT was proved as a portable and reliable device of screening patients who were suspected OSAHS.
