My mother has had COPD for many years (is from the generation that smoked before anybody knew about the damage it could cause) and I thank with all my heart the Lung Association and LUNG FORCE for all of the research that has been done and continues to be done, and the medications that have helped her so much over the years. People should know that long term use of nebulizers could cause the heart to have an extra beat. She was diagnosed with that this winter and now just uses her rescue inhalers. Everybody may not be affected by this, but I just wanted people to know. Thank you all again - you're amazing!
