Red...I am at the border of mod/severe. 48% lung function. 68 yrs old, male. I use 2L O2 at night, use a nebulizer (covered under part B), meds are Brovana x2 and ipratropium bromide x4, and use albuterol prn (also under part B).
I vol for clinical trials when avail at Mayo, they aren't so scary. I am using respiratory therapy and try to remain positive. Just remember "I have COPD, but COPD hasn't got me."
