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 Watch-PAT-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 Watch-PAT-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:
Watch-PAT-200 is an effective method in the diagnosis of OSAS.

Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
