Snoring? What is snoring? It is a snoring sound of different frequencies and pitches when inhaling or exhaling after sleeping, which many people consider as a symbol of good health and sleep. If snoring is as loud as thunder, it often affects other people’s rest, and many of them will have the phenomenon of breath-holding and apnea, that is, obstructive sleep apnea (hypoventilation) syndrome, or OSAS for short, generally refers to adults who have at least 30 times during 7 hours of sleep at night, that is, the average number of apnea per hour is more than 5, at which time the flow of air from the mouth and nose stops for at least 10 seconds, and some people are very The common symptoms include daytime drowsiness, lethargy, lack of concentration, low work efficiency, memory loss, and strange personality behavior. Nighttime sleep is characterized by thunderous snoring, restlessness, dreaminess, open-mouth breathing, and apnea. Patients with long-term persistent attacks can be complicated by hypertension, cardiac arrhythmia, and cardiopulmonary failure, and thus need to be taken seriously. OSAS is often caused by: 1) narrowing or obstruction of the upper airway (common causes include nasal polyps, deviated nasal septum, hypertrophic rhinitis, nasal tumors, adenoid hypertrophy, nasopharyngeal tumors, tonsillar hypertrophy, tongue hypertrophy, small jaw deformity, laryngeal cartilage softening, narrowing or atresia of the anterior nostril or nasopharynx, and cervical spine deformity); 2) obesity; 3) endocrine disorders (hypothyroidism, female postmenopause); 4) old age ( The site of OSAS obstruction is closely related to otorhinolaryngology. In addition to the above mentioned obstructive sleep apnea, there are also central sleep apnea (respiratory center damage, cranial injury, encephalitis, cerebral infarction, etc.), and mixed sleep apnea. Sleep apnea monitoring can be done in the hospital to understand the changes of the patient’s body during sleep, determine the nature and degree of apnea, and decide the treatment plan through the recorded heart, brain, eye, EMG and pulmonary function, oxygen saturation, etc.
