What are PFT Tests?

Pulmonary function tests (PFTs) are known to be a group of tests that are responsible to measure how well the lungs would work. 

These tests evaluate the following parameters:

  • Lung Volume Capacity
  • Rates Of Flow
  • Gas Exchange

This would also include your breathing and how effectively your lungs would bring oxygen to rest of your body.

Why Are Pft Tests Done?

The PFTs might be undertaken to determine the following parameters:

  • To assess lung function before a surgery or other procedures
  • Patients who suffer from lung or heart problems
  • Assess treatment for Asthma
  • For Emphysema
  • For COPD  and Chronic Lung issues

Types of PFT Tests

  • Spirometry: Most frequently used in lung tests which measures quantity of air inhaled and exhaled. 
    • Evaluates how quickly lungs would push the air out (expiration)
  • Body plethysmography: Amount of air left in lungs after the exhalation. 
  • Lung Diffusion Capacity (DLCO): Evaluates how thoroughly the air would go from your lungs and into your bloodstream. 
  • It decreases in Lung Emphysema and COPD and increases in Congestive Heart Failure
  • It is normal in Asthma disease.
  • Bronchial Provocation Test: Specifically to diagnose the diseases like Asthma and also its severity.
  •  Cardiopulmonary exercise stress test: Dual-purpose lung test which evaluates strength of lungs and heart.
    •  Indication: For patients with any heart diseases or lung’s related issues.
  • Pulse Oximetry Test: To measure the level of oxygen in your bloodstream.
  • Arterial Blood Gas Test: To evaluate the level of oxygen and carbon dioxide in your body.
  • Fractional Exhaled Nitric Oxide Test: Nitric oxide levels in body can rise because of a variety of the asthmatic conditions. 
    • It measures amount of nitric oxide gas present in exhaled breath.

How Does One Prepare for the Test?

Make sure you have a Valid Id Proof and Doctor’s Prescription before undergoing the test.

  • You are expected to not smoke for at least 1 hr before the PFT.
  • You are expected to not drink alcohol for at least 4 hours before the PFT.
  • You are expected to not exercise for at least around 30 minutes before the PFT.
  • Wear Lose clothes for promote easy and proper breathing.
  • You are expected to not consume a large meal at least 2 hours before the test.
  • You are instructed to not use any of the breathing medications before your test.
  • Confirm with your healthcare professional before stopping any medication.

What Is the Procedure for Pulmonary Function Test?

Each PFT test would perform to assess various factors; hence procedure for each of this test would be different.

  1. You would be asked to sit in a chair and soft clip would be put on the nose so that all of the breathing is done through the mouth.
  2. A sterile mouthpiece would then be given to you and would be attached to the spirometer.
  3. You would be asked to inhale and exhale in different ways, and multiple techniques would be used.
  4. In certain tests, you might be given a bronchodilator and then the tests would then be repeated after several minutes after your bronchodilator has been in effect.

After Care

No specific after care is required.

Risk Factors

  • Feeling Tired
  • Light-Headed 
  • Dizzy during or maybe after the test. 

Note: Patients with claustrophobia who are undergoing the plethysmography testing might feel anxious, so it’s better to inform the technician beforehand

Result Interpretation

Interpreting PFT’s

The Normal values of PFTs are seen to vary from one person to another. 

In Spirometry: FEV1: It is the Forced expiratory volume measured in one second.

FVC: It is the Forced vital capacity, or full amount of the air that could be exhaled with an effort in the complete breath 

Results of amount of air that would be inhaled and exhaled in your test will be compared to average results of people in- same age, height, sex, and race. 

The Abnormal PFT results might indicate lung and airway disease, for which even further confirmatory tests would be needed.

FAQS on Pulmonary Function Test (PFT)

How do you check pulmonary status?

The Spirometry is considered to be a type of lung function test that would measure how much air you could breathe out. 

It also helps in measuring how fast you can blow air out. During the test, the technician would ask you to take a deep breath in. Then, you would ask to blow as hard into the tube connected to small machine.

What can affect a PFT?

There are certain things that can make the PFTs less accurate

These include the following:

  • Not be able to follow the instructions for doing this test. 
  • For example- using medicines that open the airways (bronchodilators)

What should you not do before a PFT test?

Before The Test

  • You are expected to not eat, not smoke, or exercise for around 4-8 hours before the testing. 
  • You are requested to wear loose-fitting clothing.

What is the most important value on the PFT?

Most important values of PFT are as follows: 

  • Forced Vital Capacity (FVC)
  • Forced Expiratory Volume In One Second (FEV1), 
  • FEV1/FVC Ratio

The Spirometry is not able to measure your residual volume or total lung capacity.

Can PFT detect lung damage?

The PFTs are used in diagnoses of a lung condition if the patients experience symptoms such as the following:

  • Shortness of Breath - Dyspnea

PFTs might used to diagnose or help in the following:

  • Treat Lung Diseases e.g. Cystic Fibrosis
  • Lung Damage Due To The Workplace or any Home Exposure

Can PFT detect pneumonia?

The Infant PFT is usually a useful tool in being able to identify and manage the high-risk in the pediatric pneumonia patients who might further need a closer monitoring along with follow-up after the hospital discharge, with  your referral to the pulmonologist and be required to repeat pulmonary function testing.

Can a PFT detect asthma?

Measurements that taken from this test is essential in helping your doctor to diagnose asthma. The Forced Expiratory Volume is the first second (FEV 1) – measures amount of the air you could forcefully blow out in first second of your FVC. In case, this number is lower than what is considered normal, it may mean asthma.

Can PFT detect heart problems?

The Spirometry and the PFT testing are known to be a solution for the proactive cardiologist.

Spirometry is considered to be a lung-health specific diagnostic tool; it also plays an important role in assessing your cardiovascular risk, including any coronary artery disease.

What is the normal range of PFT?

Normal findings of Spirometry are considered as your FEV1/FVC ratio, If this value is greater than your 0.70, both FEV1 and FVC above value of 80% of the predicted value.

 If the lung volumes are also performed, the TLC above a value of 80% of predictive value is considered normal. 

The Diffusion capacity above the value of 75% of predicted value is also considered as normal.

How long do PFT results take?

The pulmonary function testing equips your healthcare provider to further diagnose any conditions that could affect the lungs. 

The PFTs generally don't take a long time, they aren't also not considered painful and you could also get the results in few days

How often should PFT’s be repeated?

PFTS should only be performed to three times to further ensure that your results are reproducible (that is less than the 200ml variation) and also accurate.

What is vital capacity on PFT?

The vital capacity (VC) is considered to be maximum volume that is expired after maximum inspiration. 

The VC is decreased in any of the restrictive disease but also usually normal in any obstructive disease.

What is the reliability of PFT test?

It has been demonstrated that the expert panels could reach up to 77% accuracy when predicting diagnosis based on the PFTs and with the clinical history alone.

What is an abnormal value in PFT?

The value is considered to be usually abnormal if it is approximately less than 80% of the predicted value. 

Any Normal value range might vary slightly among your different laboratories, based on any slightly different ways to determine any normal values. 

You could also talk to your healthcare provider about meaning of any specific test results.
