Abstract:
Obstructive sleep apnea syndrome (OSA) is a violation of breathing
during sleep as a result of the closure of the upper airways, leading to a
partial or complete cessation of air supply, the onset of hypoxia, and as a
result, a transient decrease in the depth of sleep, followed by restoration
of patency of the upper airways and air intake. During a patient’s sleep,
such episodes can occur hundreds of times per night, which in the pres ence of clinical symptoms is called OSAS syndrome or obstructive sleep
apnea-hypopnea syndrome.
