Just Diagnosed with Moderate COPD

This is my first post and wanted to join a community where I could get information about COPD. I am 77 years old and was first told by the VA that I had emphysema. This was about 20 years ago. They put me on some meds and and then I was put on Respimat, Combivent Respimat and albuterol rescue inhaler. I started having shortness of breath and went to a local doctor who did x-rays and said I had Pneumonia in my lower left lung. Went back after 2 weeks of meds, and found out that left lung was clear, but the lower right lung was in the beginning stage of Pneumonia. More meds. I was then sent to see a pulmonologist who order a CT scan of the lungs which came out normal. I then had the pulmonary function test which showed a baseline of 55% that went up to 63% after I was given 4 puffs of Albuterol, I think. The pulmonologist changed my medicine to Anoro, once a day, Budesonide Inhalation Suspension, twice a day, Albuterol Inhalation Suspension, and Albuterol Rescue inhaler, as needed but not together.

Sorry for such a long post but I was looking for input on this condition, what to expect and if there were thing that I could do to improve my lung function. Thanks for any suggestions or information.
