Obstructive sleep apnea hypoventilation syndrome (osahs), also known as snoring, is a chronic sleep breathing disorder characterized by recurrent complete or incomplete obstruction of the upper airway during sleep, accompanied by intermittent hypoxemia, hypercapnia and sleep structure disorders. Foreign epidemiological surveys show that the prevalence of OSAHS is 2% to 4%. The harmful effects of obstructive sleep apnea hypoventilation syndrome: OSAHS seriously affects people’s life expectancy. Overseas clinical statistics show that the 5-year mortality rate of untreated OSAHS patients is as high as 11-13%, and the 8-year mortality rate of those with an apnea and hypoventilation index (AHI) higher than 20 is 37%. OSAHS patients are two to seven times more likely to be involved in traffic accidents than control subjects. The incidence of sudden death is much higher than the normal population, about 50% of patients with sleep apnea syndrome have hypertension, 30%-50% of patients with hypertension, and 30% of patients with heart disease are caused by OSAS. Repeated apnea during sleep can be as short as 10 seconds or as long as 2 minutes, accounting for about 40% of the sleep time, and apnea can lead to hypoxemia, with oxygen saturation dropping to 60% – 80% or even lower, (1) cardiovascular diseases: heart rate disorders, hypertension, heart failure, coronary heart disease, sudden death at night (2) respiratory diseases: pulmonary heart disease, respiratory failure, asthma at night (3) neurological diseases: ischemic cerebrovascular disease, cerebral hemorrhage, dementia, memory loss, personality changes (4) endocrine diseases: diabetes, obesity, growth retardation in children (5) (6) Renal changes: proteinuria, increased nocturia (7) Other: headache, erythrocytosis, gastroesophageal reflux, etc. Treatment As the causes of snoring are complex, it endangers all systems and organs of the body. There are different treatment methods for different causes and different pathological damages. Lifestyle changes: Many lifestyle changes can improve the overall health of the body while improving OSAS. For example, snoring is often associated with obesity. The thick neck of an obese person can increase the resistance of the airway, and being overweight can cause hypertrophy of the chest wall and resistance to the downward movement of the abdominal diaphragm, which can lead to breathing problems. So losing weight is a good way. 2, quit smoking and alcohol: smoking and drinking can aggravate snoring, inhibit the activity of upper airway muscles, aggravate collapse and block the upper airway. 3, change the sleep position: due to the role of gravity when lying down to make the tongue root backward, blocking the airway, side sleep can be slightly improved. 4.Surgical treatment: Different surgical methods are adopted for different obstruction sites and different anatomical structures, which require a fiberoptic laryngoscopy to understand their specific conditions. There are tonsillectomy, palatopharyngoplasty, nasal surgery, etc. 5.Medical treatment: Since there are many patients who have many serious complications or are older, they cannot tolerate surgery. In this case, there is a ventilator, which uses the principle of positive pressure and air, and through a special setting can respond to changes in pressure according to changes in the amplitude of breathing. Once the situation of respiratory arrest occurs, the pressure then increases, opening the upper airway to form normal breathing. 6.Medication: Except for snoring caused by special causes, there is no special medicine available internationally at present Suggestions: Sleep may be too common for some people, but for snoring patients to have a sound sleep until dawn is a rare happiness. The Department of Otolaryngology at our hospital has developed sleep monitoring and treatment for obstructive sleep apnea hypoventilation syndrome. Because of the complexity of sleep disorders and the variety of hazards, many disciplines are involved. So when you yourself or your loved ones and friends have snoring, it is best to go to the hospital for a consultation, see a specialist clinic, and meet face-to-face with experts so that they can have a comprehensive understanding of your condition, and then choose different treatments under the guidance of your physician.
