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.
