Sleep apnea syndrome in the elderly

Sleep apnea syndrome (SAS) is the second largest sleep disorder after insomnia. It can cause severe hypoxemia and sleep disturbances, as well as high blood pressure, arrhythmia, cardiovascular and cerebrovascular diseases and breathing. The occurrence of diseases such as failure is closely related, and a small number of patients may die suddenly at night. In addition, due to daytime drowsiness, impaired memory and responsiveness, patients' ability to work decreased, and the incidence of accidents increased. Because of this, SAS has become an emerging marginal discipline-an important part of sleep medicine, and is increasingly receiving widespread attention from medical circles at home and abroad. In recent years, with the widespread application of non-invasive ventilation technology, breakthroughs have been made in the treatment of SAS.
