Quick diagnosis in obstructive sleep apnea syndrome : watch PAT-200

Abstract EN

Background: Obstructive sleep apnea syndrome (OSAS) is a highly prevalent 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 Watch PAT regarding stage 3 and 4 of non-REM sleep.

Very low agreement was found between PSG and Watch PAT regarding the REM sleep.

Conclusions : WatchPAT-200 is an effective method in the diagnosis of OSAS.
