What is the meaning of "shuangfeisan" in pulmonary bullae?

In layman's terms, a part of your lung can't be used, and the part with pulmonary fibrosis can't breathe.

You are aggravated by chronic bronchitis and transformed into pulmonary interstitial fibrosis!

There should be chest tightness or wheezing, especially after exercise. If it is serious, you should also take oxygen.

It's not easy to treat, hehe, but be confident and try not to use hormones or use them less. Some hospitals fool people and find the right treatment for you!
