Whenever we are active our bodies require a greater amount of oxygenated bloodflow. Thats why at rest our 02 levels are higher than when we move about or exercise Depending on your condition . 02 levels can be increased through pulmonary rehab and learnrd better breathing techniques. I had go go on 02 24/7 on two separate occasions but it was only temporary and now my 02 levels remain at 95% throughout the day as I go shopping walk at the dog park or whatever I do and use oxygen only at nite. So you can lessen your dependency.if your disease hasnt progressed too far. But we are all individual cases and everyone has medical concerns that effects us diffrrently Stay strong and continue to always question authority. We know our bodies better than anyone God Bless DAH

The disease does progress, but you can increase the O2 flow and keep your O2 saturation levels where they need to be to protect your heart and brain from damage. You may still be very SOB, but you won't have brain damage. If your doc isn't doing something to get you a higher flow, find another doc, because this one isn't worth your time or money.

My oxygen levels dropped when I walk around !

Thats why you need to keep well hydrated and keep a bottle of water with you as you use your nebulizer I always take Musinex (Kroger makes a mucus relief that is exactly the same but cost 1/3 the price make sure to get the straight Guafinesin and not the DM) Also I have a cup of lemon ginger tea with a dab of honey the combination of those 3 makes congestion breakup easily. Try it and let me know how it works for you DAH

Most of what you are experiencing is the natural progression. All the suggestions above are helpful. You have to try to do things slower than you used to. Enjoy every minute you can while you can still get out and go. Hugs
