I would use your peak flow meters and check them before exercise and during if you have problems and at the end to see where your setting at. That would tell you if your getting in the yellow or red levels during exercise.

Really good questions. I look forward to seeing all the answers. I usually just use my inhaler before I walk/exercise and again when I cannot breath any more. Sometimes I have found if I just stop, breathe deeply, slowly, don't "panic" breathe, then my lungs start functioning better. But to know how much oxygen I am getting...???? Haven't a clue!! Also, have found...just a short time doing without proper breathing/oxygen gives me an extreme headache, which I am certain is not good and may lead to other problems. ????
