What is a PFT Test?

A Pulmonary Function Test is a breathing test used to assess how well the lungs and respiratory system are functioning.

PFT can provide information about breathing patterns and lung function. The exact measurements depend on the type of pulmonary function test performed.

One of the commonly used tests is spirometry, which measures how much air you can breathe out and how quickly you can breathe it out.

Depending on the clinical requirement, pulmonary function testing can help a doctor assess respiratory function and understand whether further evaluation may be needed.

Quick Answer

• PFT= Pulmonary Function Test
• Purpose: To evaluate lung and breathing function
• Common component: Spirometry
• Who recommends it: A qualified healthcare professional based on your symptoms or clinical requirement

Why Might a Doctor Recommend a PFT?

A doctor may recommend a PFT when lung function needs to be evaluated as part of a respiratory assessment.

PFT may be considered when a patient has symptoms such as:

• Shortness of breath
• Persistent cough
• Wheezing
• Reduced exercise tolerance
• Other breathing-related concerns

PFT may also be used when a doctor needs objective information about lung function or wants to monitor an existing respiratory condition.

The test selected depends on the patient's symptoms, medical history, and the clinical question being investigated.

What Does a PFT Measure?

A PFT can provide measurements related to airflow and lung function, depending on the specific test performed.

For example, spirometry can measure:

• Forced Vital Capacity (FVC): The amount of air that can be forcefully exhaled after taking a deep breath.
• Forced Expiratory Volume in 1 Second (FEV1): The amount of air exhaled during the first second of a forced breath.
• FEV1/FVC ratio: The relationship between these two measurements, which can help healthcare professionals assess airflow patterns.

The meaning of these measurements depends on the patient's age, sex, height, symptoms, and other clinical factors.

A PFT report should be interpreted by a qualified healthcare professional rather than evaluated in isolation as a single number.

How is a PFT Test Performed?

A PFT is performed by having the patient breathe into a specialized device that records airflow and other measures of lung function.

For a basic spirometry test, the process generally includes:

1. You will be seated comfortably and given instructions by the healthcare professional.
2. A mouthpiece is placed in your mouth.
3. You will usually be asked to breathe normally for initial measurements.
4. You may then be asked to take a deep breath and exhale as forcefully and completely as instructed.
5. The test may be repeated to obtain consistent measurements.

Following the breathing instructions carefully is important because the quality of the results depends on how the test is performed.

What Happens During a PFT?

A PFT is a breathing-based diagnostic test, so your active participation is important.

During the test, the healthcare professional may ask you to:

• Breathe normally
• Take a deep breath
• Exhale forcefully
• Continue exhaling for the required duration
• Repeat the manoeuvre when necessary

You may feel temporarily tired or slightly light-headed after repeated forceful breathing. Tell the healthcare professional if you feel unwell or need a break.

The test itself does not usually involve injections or surgery.

How Should You Prepare for a PFT Test?

PFT preparation can vary depending on the type of pulmonary function test and your individual circumstances.

Follow the Centre's Instructions

Ask the centre whether you need any specific preparation before the test.

Wear Comfortable Clothing

Choose clothing that does not make breathing or chest movement uncomfortable.

Tell the Healthcare Team About Your Medications

Some medicines, particularly certain inhaled medications, may affect pulmonary function measurements.

Do not stop or change any prescribed medication on your own. Ask your doctor or the testing centre whether any medication needs to be adjusted before your examination.

Avoid Heavy Activity Before the Test

Your healthcare team may provide instructions about exercise or other activities before testing, depending on the examination being performed.

Avoid Smoking Before Testing

Smoking can affect respiratory measurements. Follow the instructions provided by your healthcare professional before the test.

Can I Eat Before a PFT Test?

PFT does not always require fasting, but preparation instructions can vary depending on the type of test.

A very heavy meal immediately before testing may make forceful breathing uncomfortable for some people.

Follow the specific instructions provided by the testing centre or your healthcare professional rather than assuming that fasting is required.

Can I Take My Inhaler Before a PFT?

Do not stop using an inhaler or other prescribed respiratory medication unless your doctor or testing centre specifically instructs you to do so.

Some pulmonary function tests are performed before and after a bronchodilator, while medication instructions can vary depending on the purpose of the test.

Before your appointment, tell the healthcare team about:

• Inhalers
• Asthma medication
• COPD medication
• Other respiratory medicines
• Any recent changes in treatment

This helps the testing team interpret the test appropriately.

is a PFT Test Safe?

PFT is generally a non-invasive test, but repeated forceful breathing can temporarily cause tiredness, coughing or light-headedness in some people.

Tell the healthcare professional before testing if you have:

• Significant breathing difficulty
• Recent chest pain
• Recent surgery
• A recent heart-related problem
• A condition that may make forceful breathing difficult

Your healthcare professional can determine whether testing is appropriate and whether any precautions are needed.

is a PFT Test Painful?

PFT is generally not painful.

The test involves breathing into a mouthpiece and following breathing instructions.

Some people may experience temporary:

• Coughing
• Tiredness
• Chest discomfort from repeated forceful breathing
• Light-headedness

If you feel uncomfortable during the test, inform the healthcare professional conducting the examination.

How Long Does a PFT Test Take?

The duration of a PFT depends on the type of pulmonary function test being performed and the number of measurements required.

A basic breathing test may be relatively brief, while more comprehensive pulmonary function testing can take longer.

The centre can provide the expected duration of your appointment for your specific test.

What Can a PFT Test Help Evaluate?

A PFT can provide objective information about how well the lungs and respiratory system are functioning.

Depending on the type of pulmonary function test, the results may help a doctor assess airflow and other aspects of breathing function.

PFT may be considered when evaluating respiratory concerns associated with conditions such as:

• Asthma
• Chronic obstructive pulmonary disease (COPD)
• Persistent breathing difficulties
• Long-term cough or wheezing
• Other suspected lung-function problems

PFT results are interpreted together with the patient's symptoms, medical history and clinical findings.

What is Spirometry?

Spirometry is one of the most commonly used pulmonary function tests and measures how much air you can breathe out and how quickly you can exhale it.

Two commonly discussed spirometry measurements are:

• FEV1: The volume of air forcefully exhaled during the first second of the test.
• FVC: The total amount of air forcefully exhaled after taking a deep breath.
• The FEV1/FVC ratio: Provides information about airflow.

These numbers should not be interpreted independently. A healthcare professional considers the patient's age, height, sex, symptoms, medical history and other relevant factors when interpreting the results.

Can a PFT Help Diagnose Asthma or COPD?

PFT can provide information that helps doctors evaluate conditions such as asthma and COPD, but the test is interpreted together with the patient's overall clinical picture.

For example, breathing tests may help identify patterns of airflow limitation.

In some situations, a doctor may compare breathing measurements before and after a bronchodilator to assess changes in airflow.

A PFT result alone does not establish a diagnosis. Your doctor determines the diagnosis based on the complete clinical evaluation.

What Do PFT Results Mean?

PFT results contain numerical measurements that describe different aspects of lung function.

Depending on the test, the report may include measurements such as:

• FEV1
• FVC
• FEV1/FVC
• Other pulmonary function measurements

Results are commonly compared with expected values based on factors such as age, height and sex.

A result outside a reference range does not automatically mean that you have a specific disease. The significance of the findings depends on the complete clinical context.

If you receive a PFT report, ask your doctor to explain the results rather than trying to diagnose yourself from individual numbers.

What Happens If the PFT Result is Abnormal?

An abnormal PFT result does not automatically identify a single condition.

Depending on the findings and your symptoms, your doctor may recommend:

• Repeat pulmonary function testing
• Additional respiratory evaluation
• Imaging such as a chest X-ray or CT when appropriate
• Further clinical assessment
• Changes or continuation of treatment

The next step depends on the individual patient's clinical situation.

Who May Need a PFT Test?

A doctor may recommend PFT when a patient has symptoms or a medical history that requires objective assessment of lung function.

Examples include people experiencing:

• Breathlessness
• Persistent cough
• Wheezing
• Reduced exercise tolerance
• Recurrent respiratory symptoms

PFT may also be useful when a doctor needs to evaluate or monitor a known respiratory condition.

The decision to perform the test should come from a qualified healthcare professional based on the patient's circumstances.

PFT Test vs Chest X-Ray – What is the Difference?

PFT and chest X-ray provide different types of information.

Which one do I need?

That depends on what your doctor needs to evaluate.

A PFT and chest X-ray are not substitutes for each other and may sometimes be recommended together.

When Should You Consult a Doctor About Breathing Problems?

Persistent or worsening breathing symptoms should be discussed with a qualified healthcare professional.

Seek medical evaluation for concerns such as:

• Ongoing shortness of breath
• Persistent cough
• Recurrent wheezing
• Reduced ability to perform usual activities
• Other unexplained respiratory symptoms

A PFT may be one part of the evaluation, depending on the clinical situation.
