Snoring at night is a very common symptom. Snoring can be divided into two kinds, one is simple snoring, many normal people will snore at night, such as overwork, deep sleep, after drinking alcohol or when lying on the back, this kind of snoring is often benign, does not cause any pathological changes or clinical symptoms, and does not need to be treated. Another kind of sleep apnea syndrome is not only snoring, but also pause, and the main thing is that the blood oxygen saturation can be found to decrease when doing sleep monitoring, so it belongs to a disease state. Sleep apnea syndrome is divided into several types, one is obstructive sleep apnea, patients often have some airway obstruction, such as nasal septal deviation, nasal polyps or tonsillar hypertrophy, the doctor of otorhinolaryngology needs to conduct some examinations for them, if they can be solved by surgical means, they can be treated through surgery; the second type is central sleep apnea, caused by some lesions of the central nervous system The third type is the mixed type of sleep apnea, where there are both central and peripheral factors. For the latter two types of sleep apnea syndrome patients, non-invasive ventilator therapy is preferred. Generally, the pressure test should be performed in a professional sleep center, and the correct pressure and correct ventilator model should be selected and worn at home for a long time.
