I am new here and searching for help and support for my husband who has Copd. He is 65 years old, a heavy smoker, a Vietnam war veteran. He can't breathe much at all, his levels are in low 90's but just can't get the air out. He can't sleep, has trouble with his cpap machine, just miserable. Just finished 3 rounds of antibiotics and steroids. Has a nebulizer, rescue inhaler, and Spiriva. His VA doctor was not much help at all, finally got him oxogen for night time use only. He now has a pulmonary DR using his insurance and hoping he helps. He has given him the antibiotics and steroids. And having him will prevent us from going 100 miles to the nearest VA hospital. I am curious about NAC and the Acapella Flutter valve. If any of you have anything on it let me know. We tried the Hydrogen Peroxide therapy but it seemed to hurt him. Running out of options.
