The drug you mentioned isn't meant to have anything to do with CO2 retention. You have a good advocate, and you should see a pulmonologist for your COPD issues. You need to use something like a bi-pap or a trilogy to help you reduce the CO2 your'e retaining. You can exercise, and yes, you should probably slow down. Your goal is endurance, not speed.

:ivingstar, go to www.copdfoundation.org and put COPD101 in the search engine. It's a series of 5 videos that explain visually what COPD is and how it affects the lungs. It includes very clear explanations of what happens with COPD, how it affects our breathing, CO2 retention and lots of other issues.

I have heard of the Trilogy Ventilator. My Doctor is old school and feels it would discourage me to breath on my own. Hello doc!... problem is I can’t breath.The medication which are pills are considered very dangerous and can cause as most meds more problems than I’m having already. My advocate is livid so has arranged for me to see another Doctor and seek a second opinion.

I get rid of co2 by exhaling, too the MAX every 5th breath! Do this 4 times twice daily!
Helps me rid of headaches 😊😊🏁
Breath with a SMILE 😊🍀🏁

thank you for asking the question, I had no idea how to treat this problem, so it was very informative to see the answers. good luck
