Pneumothorax changing PFT results?

I had a CT guided biopsy for a lung nodule, and was told there were a couple small pneumothorax from the test. A couple weeks after that I was scheduled previously to have a repeat PFT test. I got the results on MyChart, and have been very upset that it looks like my functions looks like it's dropped! My actual appointment is not for another couple weeks to discuss the test.

I wonder if a pneumothorax would skew the PFT results. Can anybody shed any light?

  1. Years ago I had a spontaneous pneumothorax way before i was ever diagnosed with copd. Nine days in the hospital with a chest tube and it healed. Thankfully it never reoccured although i worried about that for months afterwards. During the time i did not experience any notable change in my breathing in and out. It seemed largely asymptomatic except for some pain in my upper left chest and shoulder when it first happened. I am worried now that it could occur now as a result of my failing lungs. Is not the likelihood of this greater with copd?

    1. HI twovillages and thanks for your post. While we cannot provide medical advice or diagnostics over the internet (for your own safety), your concern certainly warrants a reply. In the most general of terms, a pneumothorax (or a 'couple of small' ones, as you mentioned), can have an impact on PFT results. As the pneumothoraces heal, the lung function may be expected to return to what it was prior to the lung insult. If you are upset, as you say, you may want to call the physician's office and try to have your scheduled appointment moved up to address your apprehension.
      Please do check with us and let us know how you're doing.
      All the best,
