What is PFT/ Spirometry?

Pulmonary function tests are a group of procedures that measure the function of the lungs, revealing problems in the way a patient breathes. The tests can determine the cause of shortness of breath and may help confirm lung diseases, such as asthma, bronchitis. The tests are also performed before any major lung surgery to make sure the person will not be disabled because of a reduced lung capacity


  • In a spirometry test, the patient breathes into a mouthpiece that is connected to an instrument called a spirometer
  • The spirometer records the amount and the rate of air that the patient breaths in and out over a period of time
  • For some of the test measurements, the patient can breathe normally and quietly. Other tests require forced inhalation or exhalation after a deep breath.
