I have copd. When I sit, my 02 is 95-97. When I walk it's 98. Most copders get lower not higher. Whats going on with that?
in advanced cases of COPD, the lungs are not able to provide enough oxygen during periods of higher oxygen demands such as exericise, and there may come a point where the lungs fail even at rest.
That's why you should avoid anything that might cause further lung damage
COPD (CHRONIC OBSTRUCTIVE PULMONARY DISEASE)
