1.Do I need to wear it for life? Or can it be corrected after a period of time and no longer need to wear it? Please let us think about the problem of hypertension, we all know that primary hypertension can not be cured, but as long as the medication on time can be well controlled, sleep apnea syndrome is a similar situation, ventilator can be good control of the majority of patients’ symptoms, but need to adhere to the long-term application, with weight loss, may require CPAP pressure will be reduced. With the improvement of medical science, respiratory opportunities are becoming smaller and smaller, and there may be newer positive expiratory pressure devices to facilitate the application, such as the United States provent nasal patch and our positive pressure nasal plugs and masks. 2.Is it necessary to bring the ventilator every night? Does it have any effect if I don’t bring it occasionally when I travel? There are no special circumstances that require you to wear a ventilator every day, but it is not a big problem if you don’t bring it on occasional business trips. Now the ventilator is getting smaller and more portable, if you often travel to look at the legendary ventilator, only a little larger than a thermos. 3, some patients worry about ventilator “addiction”, is it necessary? Or think about hypertension for example, someone will worry about dependence on antihypertensive drugs? No. There is no addiction to ventilators. There is no basis for addiction to ventilators, so there is no need to worry about this problem.
