Assessing Lung Function for Better Respiratory Care

Breathing problems can develop for many reasons, including asthma, allergies, respiratory infections, smoking, occupational exposure, or other conditions affecting the lungs and airways. A Pulmonary Function Test (PFT) is a group of breathing tests used to assess how well the lungs are working.

At K & K Super Speciality Hospital, our Pulmonary Function Testing services help doctors evaluate lung function and support the diagnosis and management of various respiratory conditions. The test measures different aspects of breathing, including how much air the lungs can hold, how quickly air can be moved in and out, and how effectively the lungs transfer oxygen and other gases.

PFTs may be recommended for patients experiencing respiratory symptoms or for monitoring an already diagnosed lung condition.

What Is a Pulmonary Function Test?

A Pulmonary Function Test is a non-invasive assessment of lung function. During the test, the patient breathes into a specialised device called a spirometer or other pulmonary function testing equipment.

The equipment records measurements related to airflow and lung volume. These results are then interpreted by a healthcare professional along with the patient's symptoms, medical history, and other clinical findings.

PFTs can provide useful information about whether a person's breathing pattern may be affected by an obstructive or restrictive lung condition.

What Does a PFT Measure?

Depending on the type of test performed, pulmonary function testing may assess:

• Lung volume – the amount of air the lungs can hold
• Airflow – how quickly air can be breathed in and out
• Forced expiratory volume – the amount of air exhaled during a specific period
• Forced vital capacity – the amount of air that can be forcefully exhaled after taking a deep breath
• Breathing efficiency – information about how effectively the lungs are functioning

Your doctor determines which measurements are required based on your symptoms and clinical condition.

Conditions That May Require PFT

Pulmonary Function Tests may be recommended as part of the evaluation or monitoring of conditions such as:

Asthma

PFTs can help assess airflow limitation and may be used to support the evaluation and monitoring of asthma.

Chronic Obstructive Pulmonary Disease

Patients with conditions such as chronic bronchitis or emphysema may undergo pulmonary function testing to assess airflow and monitor lung function.

Persistent Breathing Problems

Patients experiencing unexplained or persistent breathlessness, wheezing, coughing, or reduced exercise tolerance may be advised to undergo a PFT as part of their evaluation.

Occupational Lung Conditions

Individuals exposed to dust, chemicals, fumes, or other workplace substances may require lung function assessment when respiratory symptoms or occupational exposure raise concerns about lung health.

Pre-Operative Assessment

In selected patients, pulmonary function testing may be recommended before certain surgeries to assess respiratory function and assist with medical planning.

When Is a Pulmonary Function Test Recommended?

Your doctor may recommend a PFT if you experience:

• Persistent cough
• Shortness of breath
• Wheezing
• Chest tightness
• Reduced exercise tolerance
• Difficulty breathing during physical activity
• Recurrent respiratory symptoms
• A known lung or airway condition
• Symptoms associated with smoking or occupational exposure

PFTs may also be used periodically to monitor changes in lung function in patients who already have a diagnosed respiratory condition.

What to Expect During the Test

A Pulmonary Function Test is generally a simple and non-invasive procedure.

You will usually be seated and asked to breathe through a mouthpiece connected to the testing equipment. The healthcare professional will provide clear instructions and may ask you to take a deep breath and then breathe out as forcefully and completely as possible.

Several measurements may be recorded to ensure reliable results. You may be asked to repeat certain breathing manoeuvres more than once.

In some cases, your doctor may recommend additional measurements after using a prescribed inhaled medication to compare lung function before and after the medication.

How to Prepare for a PFT

Your healthcare provider may provide specific instructions before the test. Depending on your individual circumstances, you may be advised to:

• Avoid smoking before the test
• Avoid strenuous exercise immediately before testing
• Wear comfortable clothing that does not restrict breathing
• Avoid a heavy meal shortly before the test
• Follow your doctor's instructions regarding inhaled medications

Do not stop any prescribed medication unless your doctor or testing team specifically advises you to do so.

Is a Pulmonary Function Test Safe?

PFT is a non-invasive test and is generally well tolerated. Because the test involves repeated deep and forceful breathing, some people may experience temporary light-headedness, coughing, or shortness of breath during or immediately after the test.

The test should be performed under appropriate medical supervision, particularly for patients with significant respiratory or other medical conditions.

Inform the healthcare team about your medical history, recent illness, chest pain, breathing difficulties, or any other relevant health concerns before testing.

Understanding Your PFT Results

PFT results are interpreted by comparing the measured values with expected values based on factors such as age, height, sex, and other relevant clinical factors.

The results may provide information about airflow limitation, lung volumes, and overall respiratory function. Your doctor will interpret the findings together with your symptoms, medical history, physical examination, and other investigations.

A PFT result alone does not always establish a diagnosis. Additional evaluation may be required depending on the findings.

Monitoring Lung Health

Pulmonary Function Testing can also be useful for monitoring respiratory conditions over time. Repeated testing may help doctors assess changes in lung function and evaluate the response to treatment when clinically appropriate.

Regular follow-up can be particularly important for patients with chronic respiratory conditions or ongoing exposure to factors that may affect lung health.

Respiratory Diagnostic Support at K & K Super Speciality Hospital

At K & K Super Speciality Hospital, our Pulmonary Function Testing services provide valuable diagnostic support for patients with respiratory symptoms and lung-related conditions. The test helps doctors understand how effectively the lungs are functioning and supports appropriate clinical decision-making.

Our team focuses on providing clear instructions and a comfortable testing environment while ensuring that the examination is performed according to the patient's medical requirements.

Breathe Better with the Right Evaluation

If you have persistent breathing difficulties, coughing, wheezing, or reduced exercise tolerance, speak with your doctor about whether a Pulmonary Function Test may be appropriate for you.
