Obstructive Sleep Apnea Hypoventilation Syndrome I. What is Obstructive Sleep Apnea Hypoventilation Syndrome? Obstructive Sleep Apnea Hypoventilation Syndrome (OSAHS) is a sleep-breathing disorder of unknown etiology, characterized by nighttime snoring with apnea and daytime sleepiness. The repeated episodes of nocturnal hypoxia and hypercapnia caused by apnea can lead to hypertension, coronary heart disease, diabetes mellitus, cerebrovascular disease and other complications, as well as traffic accidents, and even sudden death at night. Therefore, obstructive sleep apnea hypoventilation syndrome is a potentially fatal sleep breathing disease. Second, the main cause of morbidity? The direct pathogenesis of OSAHS is the narrowing and obstruction of the upper airway, but its onset is not simple airway obstruction, but actually upper airway collapse, accompanied by respiratory central neuromodulatory factor disorder. There are many causes of upper airway narrowing and obstruction, including nasal septum curvature, tonsillar hypertrophy, soft palate overgrowth, mandibular arch stenosis, mandibular retraction deformity, temporomandibular joint ankylosis, small jaw deformity secondary to joint ankylosis on both sides in a few cases, megalolingualism, and posterior displacement of the hyoid bone. In addition, obesity, upper airway tissue mucous edema, and oropharyngeal or hypopharyngeal tumors can also cause OSAHS. the etiology and pathogenesis of OSAHS need to be further researched. Warm tips to warn the symptoms of obstructive sleep apnea hypoventilation syndrome? 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 obstructed, and snoring is a characteristic manifestation of OSAHS. This kind of snoring is different from simple snoring, the volume is large and very loud; the snoring is irregular and intermittent. 2.Daytime sleepiness: it is manifested as daytime weakness or drowsiness. 3.Apnea occurs during sleep: the heavier ones often have breath-holding at night, or even sit up suddenly, sweating profusely, with a sense of near death. 4.Increased nocturia: increased nocturia at night due to apnea, and enuresis in individual patients. 5.Headache: due to hypoxia, patients develop morning headache. 6, personality changes and other systemic complications: including temper tantrums, intelligence and memory loss and sexual dysfunction, etc., serious cases can cause hypertension, coronary heart disease, diabetes mellitus and cerebrovascular disease. Dietary guidance should be light, eat more fruits and vegetables, reasonable combination of meals, pay attention to nutritional adequacy. V. Effective treatment? The treatment of OSAHS is divided into two categories: non-surgical treatment and surgical treatment, in addition to lying on the side, quitting smoking and alcohol, and weight reduction for obese people.
