I have been a heavy smoker most of my life (50-70 a day) I began at the age of 12 and carried on until I was 64. When I was 61, I had pneumonia of one lung and was treated accordingly.  A few years later, I began to have problems with my breathing. Had a respirometry and was diagnosed with COPD.  I am presently using PRIRIVA, SYMBICOR, ATROVENT and VENTOLIN.  A few weeks ago, I was down with a severe cold and a fever of 38.8ºC The cough was so violent that I may have developed a slight hernia. That I will have it checked later on this month. I have totally quit smoking 4 years ago. I am wondering if an oxygen-replacement therapy would be beneficial, as I am still very active workwise.

Thanks for your kind advice.
