Look up AIRPHYSIO looks like inhaler take breath normal not through the decide then put device to mouth and exhale the pressure of the air pushes up a ball that is heavy enough to bounce just enough to pulse the air your breath out of your lungs effectively breaking up mucus that could be clogging ventricles or whatever in their gets clogged. Anyway not only does this produce all the mucus after a few days of using it regularly for all of us that got lung problems either from covid or not. If it's not a disease that you are stuck treating for life then just like with pneumonia you have to do breathing in deep as you can hold hold hold slowly breath out. You need to work your lungs get them back to strength and have to get them back to normal size expanding them by exercising them. This with a yogurt a day specific digestive enzyme zinc and a few other pretty expensive supplements ended my 18 month nightmare in the dark silence in a week. I used THORNE supplements. I noticed effects right away. Olive leaf and oregano supplements can help your lungs but taking NAC, reservstrol, quercetin, zinc, increasing the antioxidant glutathione taken with vitamin C to keep it active, vitamin D3, cinnamon, antihistamine and antiinflammatories. Iron and keep electrolytes up coffee enema once a day for 30 days 2x a week after that a yogurt a day to keep good guys in my gut which helps immune system and also aids in absorption of the supplements.

Not in healthcare just a cook who's not allowed hospital trestments. Had to learn to heal myself after abscess nearly killed me luckily my best friend iccthamol ointment saved me a long with oregano supplements but I try to get olive LEAF if I can. Peppermint is an expectorant. Should also help break up mucus if drinking in hot hot tea and let that steam in those lungs. What helps me is having a friend smack my back on the sides the smacking like you would burp a baby but harder for adult and hard enough (shouldn't hurt at all) to lightly pound the lungs vibrate you'll even begin to feel the mucus in your lungs swirl around and at this point gravity can be helpful if you can cough it up try to get it to come down... By hanging so your lungs are upside down. This helps too
