Sleep apnea: The most common type of sleep apnea is obstructive sleep apnea (OSA). Regardless of the severity of the condition, the obstruction is basically in the upper airway of the pharynx, a passage surrounded by soft tissues, and snoring is also caused by the vibration of the soft palate in this area. There are many reasons for OSA, besides the local narrowing caused by the soft tissues of the upper respiratory tract or new organisms, age, obesity, appearance (jaw and facial bone development, such as a small jaw by birth), some diseases (such as hypothyroidism) and many other factors may act together to cause snoring and apnea. Therefore, it is difficult to solve all the factors regardless of the treatment taken. Therefore, except for those caused by specific diseases, sleep apnea, like all chronic diseases, is theoretically incurable. Even if some people temporarily improve with treatment, they may relapse with the increase in age and weight of the diagnosis. However, it does not matter, formal treatment can bring the symptoms under good control and has some protection for the heart, brain, blood vessels and important internal organs. Sleeping with a ventilator is one of the most effective treatments for moderate to severe OSA. It is based on the principle of continuous positive airway pressure through a nasal mask or facemask to hold the upper airway in place, eliminate soft palate vibration and prevent upper airway collapse, ideally eliminating snoring and apnea, and thus eliminating nighttime hypoxia. However, this is also an allopathic treatment. Just as patients with hypertension and diabetes require regular daily medication, patients with OSA are required to sleep with a ventilator every day, and the longer they are on the ventilator each night, the better the protection for their bodies. An average of 4 hours or more per night is usually required. Will I be dependent on the ventilator? Actually, OSA patients are not unable to breathe, their apnea is only due to the blockage of the upper airway, the respirator for OSA treatment is to provide a pressure to hold up the upper airway so that it does not collapse or block.
