How to prepare for a PFT

  • Do not eat a heavy meal before the test.
     
  • Do not smoke for 4-6 hours before the test.
     
  • You will get specific instructions if you need to stop using bronchodilators or inhaler medications.
     
  • Your cooperation while performing the test is crucial in order to get accurate results. A poor seal around the mouthpiece of the spirometer can give poor test results that can't be interpreted. Please follow ALL instructions given to you by your doctor.
