Can someone tell me what this means.  They were looking for asthma or emphasema and so on.  I am on 3 inhalers and have trouble breathing especially in hot and humid weather, dusty or dry places and so on.

to me the tests look pretty good for the flows however they do not show pre & post results after having a bronchodilator administered.  Talk to you doc and ask about a methacholine challenge.  

There could be some concern regarding the lung volume measurements being below predicted.

Did you take your inhalers prior to the tests?  If you did it can create erroneous results.

In any case, its best to talk these over with a pulmonologist.

I agree with ruthven, it is best to go over these with your pulmo.
