Pulmonary Function Testing Near Me: How Should I Prepare? How is the Test Performed? Why Would I need a PFT?

How should I prepare for my Pulmonary function test?

  • Avoid smoking for at least 4 hours before the test.
  • Eat light
  • If you are on inhaler medications, your healthcare provider should give you specific instructions regarding whether or not you should stop use before the PFT.

How are PFTs performed?

  • Through spirometry, which measures airflow and can evaluate a range of lung diseases by recording the rate of air you breathe in and out.
  • Through Lung volume measurement, which often requires a patient to sit in a sealed area that actually resembles a phone booth while breathing into a mouthpiece that measures lung volume.
  • To measure diffusion capacity, they may have you breathe in a tracer gas for one short breath to estimate how well your lungs move oxygen from the air into the bloodstream.
