@wangling Hello there Ling… long time no talk…

The squeeze gets out the stuff in the deep crevices down below in the lungs that nebulizing does not reach ….believe me when I tell you it is life-changing. If that stuff doesn’t come out, which it does not come out from normal nebulizing , then the bacteria has a place to grow. I ended up in the hospital two times before I learned how to do it ; and now I haven’t been in the hospital for three years and my CT scans are excellent, no progression …and even has cleared up some mucus plugs and stuff …and also my bronchiectasis has not progressed.
Lung Matters is where I learned everything I know…not from doctors AT ALL. I highly recommend you join! regards. Bon
