"Doing better than I have been. I have early stage 4 COPD with FEV1 levels in the high 20s after a bout with bronchitis. Slowly I've started exercising again and now have worked my way back up to being able to do 5 miles on a stationary bike. I've recently been using my POC while exercising indoors but not outdoors. When walking my O2 sats sometimes fall to 89 or so. Is this dangerous? "
