Clearing lung technique I found by accident

I just recently started going to Mayo Clinic. My Dr. Scheduled a CT Scan and some pulmonary tests on the 28Th. I had been diagnosed with bronchiecstasis and mac lung by my pulmonologist in Tallahassee but all they were addressing was the mac lung and doing nothing about clearing my lungs so the Mayo clinic was set up as a second opinion. When they put me through CT scan on my back with knees bent I noticed mucus came right to my throat. I had been nebulising with albutrol and 3% saline since my first appointment on 2/11 and although I felt good after albutrol I was still not coughing up much sputum even after flutter valve. After CT I had an hour to waste before next test I went to my car and I coughed up a huge amount of sputum. I thought wow I hope I have more for my sputum test. After my pft I sat for 20 minutes with saline and produced nothing. I told tech about what happened after CT scan and she put me in a recliner for 5 minutes and I was able to bring up sputum. I googled this and it is an actual technique that I am now using everyday with success every time. After nebulising or if you can if mucus gets in your throat Lie on your back with your hips on two pillows and knees bent. Your head should slightly off bed. Do this for 5-10 minutes and the mucus is in your lower lungs will drain to your throat. I also clap my lower lungs to get it moving more. I also put my hands over my head and inhale and hokd it several times just like CT scan. It might not work for everyone but it works every time for me with large amounts of sputum that I have not been able to bring up even with a flutter valve. Google it.
