Spirometry, the most common PFT test, involves the patient’s breathing into a mouthpiece. This mouthpiece is connected to spirometer, an instrument that measures the amount of air you breathe and the rate at which you breathe over a set period of time. You might be asked to breathe normally for or breathe heavily with forced inhaling and exhaling depending on the nature of the measurement.

For body plethysmography, patients are seated in a transparent, sealed box and asked to breathe into a mouthpiece. The lung volume is determined with the help of the variation of pressure inside the chamber. Another procedure for this lung function test involves the patient’s breathing helium or nitrogen gas through a tube. This tube is attached to a chamber and in which the concentration of the helium or nitrogen gas is measured to determine the volume of the lungs.

For the measurement of lung diffusion capacity, patients are asked to breathe in a harmless gas, also called a tracer gas, mostly for just a single breath. The amount of gas that the patient breathes out is measured and the difference between the amount of gas inhaled and exhaled is determined. This difference allows the doctors to determine how effectively oxygen is passed from the lungs to the bloodstream.

A patient can go home immediately after the test if the results are normal. However, in case the results are abnormal, you may need to stay back to consult the doctor.

A PFT Test is a safe procedure generally. However, the procedure may lead to some complications, such as:

• Light-headedness or fainting due to the heavy and rapid breathing
• For an asthmatic patient, taking this test might lead to an asthmatic attack
• In very rare cases, this procedure may result in a collapsed lung
• Individuals who have recently had a heart attack or some other heart disease, undergone a chest, abdominal or eye surgery or are suffering from a respiratory infection are advised not to take a pulmonary function test.
