What are your thoughts on the test.Im 44 i have Pulmonary fibrosis and when im doing normal daily living stuff like up and down stairs. Walking out and about with slight inclines i like to do green bowling . i love archery and dancing with my partner. All these real time activities which are part of what makes me tick . these make my sats drop to between 87 .89 making me short of breath and upset and not being able to do things and compete to the best i can. Doc see my sat while sat in his treatment room at 95. 96 thats ok he says. Im having another 6 min walk test which my sats go to 93.94 this is no a true acount of my activities . so frustrating i cant lose weight just walking i nedd to be more active. I personally think its a false teat for a more younger active person . if your much older its provley a true reflection .your thoughts .
