Abstract :
Background: Obstructive sleep apnea syndrome (OSAS) is a highly prevelant disorder and found in approximately
2-4% of middle-aged adults.
Objectives: To assess the efficacy of WatchPAT-200 in the diagnosis of obstructive sleep apnea syndrome (OSAS).
Patients and Methods: Patients suspected of having OSAS underwent overnight Level I polisomnography and simultaneously
wore WatchPAT-200 in the sleep laboratory.
Results: 51 adult patients included in the study. The average age was 45.3±10.5 years and the average body mass index
(BMI) was 29.4±4.0 kg/m2. There was a high agreement between PSG and Watch PAT regarding apnea-hypopnea index,
respiratory disturbance index and oxygen desaturation index. Significant but a low agreement was found in stage 1
and 2 of non-REM sleep when two methods compared. No agreement was found between PSG and WatchPAT regarding
stage 3 and 4 of non-REM sleep. Very low agreement was found between PSG and WatchPAT regarding the REM sleep.
Conclusions: WatchPAT-200 is an effective method in the diagnosis of OSAS.
