Which brand of ventilator is good? What should I pay attention to when buying a home ventilator?

Most people who use ventilators at home are people with sleep apnea syndrome, which is common in middle-aged men. For example, my father snores even after a short nap. Since I realized the possible harm of snoring, I began to learn and understand which brand of ventilator is good, hoping to improve my father's snoring through ventilator treatment. I summed up three things that need special attention when buying a ventilator. First, the overall movement of the ventilator. After all, most of the use scenarios of the ventilator are used in conjunction with sleeping at night, and if the sound is too loud, it will affect the rest; The second is the sensitivity of the ventilator, which can keenly detect the speed of the ventilator's pressure rise and fall, so as to have a better therapeutic effect; The third is the size of expiratory resistance, which directly determines the comfort of wearing a ventilator. Based on the above factors, I finally bought my father a ventilator of Yuyue Medical

4-level noise reduction technology, which operates without noise and provides comfortable and stable pressure. The expiratory resistance will be adjusted with the user's breathing frequency, so it is very comfortable to use. Since my father wore the ventilator of Yuyue Medical, the snoring situation at night has been obviously improved. Therefore, if there are snoring maniacs around you, the awareness of improving snoring must be established. Which brand of ventilator is good? I think the old-fashioned domestic Yuyue medical treatment is quite good, with good curative effect and high cost performance, and after-sales service is also in place. My dad often asks the official WeChat WeChat official account for answers and help if he has any problems in use.
