What are the one or two key numbers on my PFT report?

[Brian27]

I have asthma, and my new pulmonologist ordered a full set of pulmonary function tests. I got a copy of the results, but the numbers and graphs are confusing. I know I need a professional for pulmonary function test interpretation, but I'd like to understand the basics so I can have a better conversation at my follow-up. What are the one or two key numbers on that report that I should focus on trying to understand first?
