Sleep apnea syndrome is defined as more than 30 repeated episodes of apnea for more than 10 seconds each during 7 hours of sleep per night; or an average of 5 or more episodes of apnea and hypoventilation per hour during all-night sleep. It can be divided into central, obstructive and mixed, with obstructive being the most common, and the treatment is as follows: 1. Risk factor treatment: Risk factors for obstructive sleep apnea syndrome include male, increasing age, obesity, family history, history of alcohol consumption and abnormal airway anatomy in the pharynx due to nasopharyngeal diseases, etc. Interventions for related factors, such as weight loss and alcohol cessation, in addition to avoiding excessive excitement before bedtime, overfull diet, and In addition, avoid excessive excitement before bedtime, full diet, sleep in the side position, etc. will also help to improve the symptoms. 2, targeted treatment: sleep apnea is due to soft tissue hypertrophy of the pharynx, pharyngeal muscle tone decline, airway shortening and other factors leading to reversible obstruction of the upper airway during sleep or hypoventilation caused by apnea or hypoventilation, severe cases repeatedly wake up. Continuous positive airway pressure ventilation can make the patient’s airway open and avoid obstruction. Certain patients with oral malformations need to use oral orthoses to increase respiratory air flow. 3.Encourage such patients to lose weight: exercise more, improve physical quality, avoid prolonged supine, use corticosteroid nasal drops to keep the airway open, and if necessary, give oxygen or use ventilator. 4.Surgical treatment: If the obstruction is really serious and localized, with clear parts, it can be directly surgically removed to achieve the effect of radical cure. In summary, to treat sleep apnea syndrome, first of all, we need to find our own risk factors and etiology, so as to intervene in the treatment, after the ineffective need to choose the treatment of continuous positive pressure airway ventilation through the nose, if necessary, surgical operation.
