There are many causes of OSA, besides the soft tissues of the upper airway or the presence of neoplastic organisms that cause localized narrowing, age, obesity, looks (maxillofacial bone development, such as small jaws from birth, etc.), some illnesses (e.g., hypothyroidism), and many other factors may all work together to cause snoring, apnea, and so on. Therefore, it is difficult to address all factors regardless of which treatment is taken. Therefore, sleep apnea, like all chronic diseases, is theoretically incurable, except when caused by specific diseases. Even if some people get better temporarily with treatment, it may recur with the age and weight of the diagnosis. However, it doesn’t matter; regular treatment can keep the symptoms well under control and offer some protection to the cardiovascular system and vital internal organs. Sleeping with a ventilator is the most effective of the various treatments for moderate to severe OSA. Its principle is to continuously give a positive pressure to the airway through the nasal mask or face mask, to hold the upper airway, to eliminate the soft palate vibration and to prevent the upper airway from collapsing (see the figure below), which ideally can basically eliminate snoring and apnea, thus eliminating the lack of oxygen at night. However, this is an allopathic treatment, and just as patients with high blood pressure and diabetes need to take regular daily medication, patients with OSA need to be on a ventilator every day while they sleep, and the longer they are on the ventilator each night, the better the protection they will have. An average of 4 hours or more per night is usually required. In addition, almost every patient has asked: will the ventilator be dependent? Don’t be able to breathe without it someday! In fact, OSA patients are not unable to breathe, their apnea is only because the upper airway is blocked, the treatment of OSA ventilator is to rely on a stream of air to provide a pressure to hold up the upper airway, so that it does not collapse or blockage, the breathing itself is still dependent on the patient to complete their own, and does not rely on the machine, so there will be no respiratory dependence. Ventilators allow patients with moderate to severe OSA to sleep without worry, and they are also a “household appliance” for daily life. Let’s all work together to make life with a ventilator easier!
