bb729 check out the Zephyr Endobronchial Valve for Emphysema. It at least shows some promise. Myself I wish we could all go to a US clinic and have all the options of stem cell therapy available to us and covered by insurance. I would rather die trying to improve my breathing than just accept my fate. When I am finally able to go for stem cell therapy I will update you all on my progress or lack of progress no matter which way it goes I am willing to try and I have so much faith that this is the right treatment for me. I have faith that God has led me to do this and will help me find a way.
