Pulmonary Function Tests (PFTs)
Pulmonary Function Tests (PFTs) are critical diagnostic tools used to evaluate lung function in children. These tests provide essential insights into respiratory health, helping diagnose, monitor, and manage a variety of conditions, including Asthma. Among the various Pulmonary Function Tests (PFTs), Spirometry and Impulse Oscillometry are particularly valuable for children due to their reliability and adaptability. This section deals with an overview of Pulmonary Function Tests (PFTs), with subsections dealing with individual tests.
What Are Pulmonary Function Tests?
Pulmonary Function Tests are non-invasive procedures that measure how well the lungs work. They assess:
- Lung Volumes: The amount of air the lungs can hold.
- Airflow: How quickly air moves in and out of the lungs.
- Gas Exchange: The efficiency of oxygen and carbon dioxide transfer between the lungs and blood.
PFTs are particularly useful for diagnosing respiratory conditions, monitoring disease progression, and evaluating the effectiveness of treatments.
Key Types of Pulmonary Function Tests for Children
Spirometry:
- Measures the amount and speed of air a child can inhale and exhale.
- Commonly used to diagnose and monitor asthma by identifying airflow obstruction and bronchodilator responsiveness.
Impulse Oscillometry (IOS):
- Ideal for young children who may struggle with spirometry.
- Measures airway resistance and reactance during normal breathing, providing detailed information about both large and small airways..
Body Plethysmography:
- Provides precise measurements of lung volumes and airway resistance.
Diffusion Capacity Tests:
- Assess how efficiently oxygen passes from the lungs into the blood.
Exercise Challenge Tests:
- Used to evaluate exercise-induced asthma or bronchoconstriction
Why Are Pulmonary Function Tests Important for Children?
- Early Diagnosis: Detects respiratory issues like asthma or restrictive lung diseases early.
- Treatment Monitoring: Evaluates the effectiveness of medications, such as bronchodilators or inhaled corticosteroids.
- Individualized Care: Provides data to tailor treatment plans to the child’s specific needs.
Applications of Pulmonary Function Tests in Pediatric Conditions
Asthma:
- Diagnoses and monitors asthma severity and control.
- Assesses bronchodilator responsiveness to optimize treatment.
Chronic Lung Diseases:
- Evaluates conditions like interstitial lung disease, cystic fibrosis, bronchopulmonary dysplasia, etc.
Neuromuscular Disorders:
- Monitors respiratory muscle strength and lung function in conditions like muscular dystrophy, myopathies and spinomuscular atrophy
Unexplained Symptoms:
- Investigates chronic cough, wheezing, or shortness of breath.
Pulmonary Function Tests (PFTs) are indispensable for evaluating and managing respiratory health in children. From Spirometry to Impulse Oscillometry, these tests offer a comprehensive understanding of lung function, aiding in the diagnosis and management of conditions like Asthma. The individual pulmonary functions are detailed in the sub sections.
Conclusion
Pulmonary Function Testing Facility at BLK MAX and Children's Chest Clinic
Children’s Chest Clinic and Division of Pediatric Pulmonology at BLK-MAX Hospital we have a state of the art pulmonary function testing equipment from performing various pulmonary function tests in children including spirometry, impulse oscillometry, diffusion capacity, lung volumes and treadmill challenge spirometry. The equipment has computer animation programs or computer games to make these tests easier for children.
We have specifically trained Lung Function physiologists who help kids to perform various lung function tests. Dr Ankit Parakh takes special interest in getting these tests done.

Frequently Asked Questions (FAQs)
1. At what age can children undergo Pulmonary Function Tests?
PFTs like spirometry can typically be performed in children aged 5 years and older. Tests like Impulse Oscillometry are suitable for younger children as young as 3 years old.
2. Are Pulmonary Function Tests painful or invasive?
No, PFTs are non-invasive and painless. They involve breathing into a device and are safe for children.
3. How long do Pulmonary Function Tests take?
The tests usually take 30-60 minutes, depending on the type of test and the child’s ability to perform it.
4. Can PFTs diagnose asthma in children?
Yes, spirometry and other PFTs are key tools for diagnosing asthma by measuring airflow and detecting airway obstruction.
5. How should parents prepare their child for a Pulmonary Function Test?
Parents should ensure the child avoids heavy meals, certain medications, and vigorous exercise before the test. Comfortable clothing is also recommended.
