My dad has been living with COPD (emphysema) for a number of years. He has had many appointments with the Respiratory clinic, but is now managing on a nebuliser, inhaler and water tablets to keep fluid out of his lungs. He is breathing better than he has in years, and doesn't need oxygen. The only thing we have to be careful with is if he picks up a cough or a cold he is more prone than most people to getting chest infections. If we don't catch them early enough it can take several doses of strong antibiotics to clear them up. Your husband sounds in much better general shape than my dad too. Good luck, and remember that it is a disease to live with, rather than to die of.
