i'n 70 years old and been in the COPD fight for 10-15 years. I just finished pulmonary rehad and increased my o2 levels to 94-95. my big problem is I have had 3 exacerbation over the winter. Flairs result in ER visit, no admittance. I spend the next week coughing my head off waiting for the antibiotics t work. not on home o2, I only get sick in the Ohio winters. Short of moving, how can I help my situation. All comments appreciated
