Patients with moderate to severe sleep apnea syndrome are suitable for non-invasive ventilators, i.e., they wear a ventilator every day they sleep. The regular use of a ventilator is more than 5 days a week for at least 4 hours each night to have a therapeutic effect. Nowadays, in order to facilitate more incumbents to use non-invasive ventilators, ventilator companies have developed non-invasive ventilators that are as big as a mouse, and their functions are gradually being improved, for example, when there is no power supply in the field, solar energy storage panels can be used to maintain the function. Once non-invasive ventilator treatment is used, it is recommended to stick to it for clearer and better treatment results. Some patients who have been treated for a period of time, such as those who are particularly heavy, have lost weight rapidly after treatment for a period of time, for example, their original weight was 200kg, but after treatment, it is now 80-90kg, and the weight of more than 100kg is gone, which means that the symptoms are completely relieved. If the weight can be kept from increasing, the non-invasive ventilator can also be stopped. So currently there is a method of treatment besides the above mentioned, namely surgical weight reduction surgery. There are many young people who do not want to wear a ventilator for the convenience of choosing surgical weight loss surgery but doctors recommend long-term adherence to ventilator treatment.
