I had a pulmonary function test on monday and something makes me think they may have done something wrong. The Doctor told me to blow into the machine and then I walked on the tredmill (sp) he told me to tell him when the pace was a comfortable walking at so I did. Then he raised it to more of an incline plane for 10 min. Nothing happened! I get more out of breath running/walking up a flight of stairs. I thought i would at least be running or walking fast. Is this how they always do it? They said my lungs capicity(?) was above normal for a teen and low for an adult but that was okay. What do you think? my peakflow or FV1 thing barley moved/dipped...........
