Apnea syndrome does not necessarily involve the use of a ventilator. Apnea mainly refers to sleep apnea, which is called sleep apnea when more than 30 pauses in breathing occur during a 7-hour sleep, and each pause in breathing, that is to say, an interruption in airflow, lasts for more than 10 seconds. It leads to serious consequences, which can cause the patient to suffer from a series of symptoms such as hypoxemia and hypercapnia, and some people may suffer from dizziness, fatigue, or even nighttime convulsions and respiratory arrest. Treatment is mainly divided into several types, obstructive sleep apnea, central sleep apnea, mixed sleep apnea. Obstructive type, obese patients are prone to appear, after obesity head muscles, fat is more formed extrusion, it is recommended to lose weight, exercise; laryngeal muscles are more flaccid. There are palatal hypertrophy, tonsillar hypertrophy patients recommended side-lying position, side-lying position than the supine position caused by apnea has some relief, supine position is most likely to cause sleep apnea, the more serious can be localized surgical treatment. Central sleep apnea, to address the cause of treatment, the more serious patients with respiratory failure before recommended treatment with a ventilator.
