Purpose
Obstructive sleep apnea syndrome (OSAS) is the most common form of the breathing violation during sleep.
The syndrome often remains undiagnosed.
This condition is characterized by the presence of snoring,
repetitive partial or complete cessation of breathing during sleep,
long enough to reduce the level of oxygen in the blood,
rough sleep fragmentation and excessive daytime sleepiness.
The prevalence of OSAS is 5-7% of the population older than 30 years.
Severe forms of the disease affect approximately 1-2% of the specified group of persons.
Currently OSAS is regarded as an independent risk factor for various cardiovascular diseases.
The most common criterion of apnea severity is the sleep apnea-hypopnea index,
but there are some other parameters also indicating the severity (e.g.
the level of oxygen saturation SaO2).
The aim of the study was to compare the upper airway section area in patients with obesity and sleep apnea syndrome who have oxygen blood saturation (SpO2) level less and more than 75%.
