Obstructive sleep apnea hypoventilation syndrome (OSAHS) I. What is obstructive sleep apnea hypoventilation syndrome? Obstructive sleep apnea hypoventilation syndrome (OSAHS) is a sleep breathing disorder of unknown etiology, with clinical manifestations of nocturnal sleep snoring with apnea and daytime sleepiness. The recurrent episodes of nocturnal hypoxia and hypercapnia caused by apnea can lead to complications such as hypertension, coronary heart disease, diabetes and cerebrovascular disease, traffic accidents, and even sudden death at night. Therefore, obstructive sleep apnea hypoventilation syndrome is a potentially lethal sleep breathing disease. What are the main causes of OSAHS? The direct pathogenesis of OSAHS is the narrowing and obstruction of the upper airway, but its pathogenesis is not simple airway obstruction, but actually the collapse of the upper airway, and is accompanied by impaired central respiratory neuromodulation factors. There are many causes of upper airway narrowing and obstruction, including nasal septum curvature, tonsillar hypertrophy, soft palate overgrowth, mandibular arch narrowing, mandibular recession deformity, temporomandibular joint ankylosis, and in rare cases, micromandibular deformity secondary to joint ankylosis on both sides, megalingualism, and hyoid retroversion. The etiology and pathogenesis of OSAHS need further study. 3.Warm Tips Be alert to the symptoms of obstructive sleep apnea hypoventilation syndrome? 1. Snoring: Snoring during sleep is caused by the vibration of the soft palate when air passes through the oropharynx. Snoring means that the airway is partially narrowed and blocked, and snoring is a characteristic manifestation of OSAHS. This kind of snoring is different from simple snoring, the volume is high and very loud; the snoring is irregular and intermittent from time to time. 2.Daytime drowsiness: It is manifested as daytime weakness or drowsiness. 3. Apnea occurs during sleep: the heavier ones often appear to hold their breath at night, even sitting up suddenly, sweating profusely and having a sense of near death. 4.Increased nocturnal urination: Nocturnal urination increases at night due to apnea, and individual patients experience enuresis. 5.Headache: Due to lack of oxygen, patients develop morning headache. 6.Changes in personality and other system complications: including irritability, intellectual and memory loss and sexual dysfunction, etc. In severe cases, it may cause hypertension, coronary heart disease, diabetes and cerebrovascular disease, IV. V. Effective treatment methods? The treatment of OSAHS is divided into two categories: non-surgical treatment and surgical treatment, in addition to side lying, smoking and alcohol cessation, and weight reduction for obese people.
