PFT question

I had a pulonary funtion test recently and haven't gotten the results back yet. What abnormalities should I be looking for when I do get the results.  Also, I noticed that at the bottom of the screen on the monitor, in red it said "possible leakage" does that mean a problem with the machine or me?  Thank you
