Spirometry in Children
Spirometry is an essential diagnostic test that plays a pivotal role in assessing lung function in children. It is a type of Pulmonary Function Test (PFT) that measures how much air a child can inhale and exhale and how quickly they can do so. This non-invasive test is especially valuable in diagnosing and managing conditions like Asthma and other respiratory disorders. This section deals with an overview of spirometry in children highlighting its importance, how it is performed and utility in management of asthma in children.
What is Spirometry?
Spirometry is a simple, painless test that evaluates lung function by measuring two primary parameters:
- Forced Vital Capacity (FVC): The maximum amount of air exhaled after a deep breath.
- Forced Expiratory Volume in 1 Second (FEV1):The amount of air exhaled in the first second of a forceful breath out.
These measurements provide critical insights into the functioning of a child’s lungs, aiding in the diagnosis and management of respiratory conditions.
Importance of Spirometry in Children
Children often find it challenging to express their respiratory symptoms, making objective tests like spirometry invaluable. It helps in:
- Diagnosing Asthma: Identifies airflow obstruction and its reversibility after bronchodilator use.
- Differentiating Respiratory Disorders:Helps distinguish between asthma and other conditions like restrictive lung diseases.
- Detecting Early Respiratory Issues:Monitors respiratory status and identifies potential problems before they worsen e.g. in children with neuromuscular disorders like duchenne muscular dystrophy (DMD), congenital myopathies, spinal muscular atrophy (SMA).
- Monitoring Treatment Effectiveness: Tracks how well a child’s respiratory condition is responding to prescribed therapies.
Performing Spirometry in Children
Conducting spirometry in children requires a tailored approach to ensure accuracy and cooperation. The steps include:
- Preparation: The child is seated comfortably, and the procedure is explained in simple terms.
- Demonstration: A healthcare provider demonstrates the proper technique for inhaling and exhaling.
- Test Execution: The child takes a deep breath, seals their lips around the mouthpiece, and exhales forcefully and completely into the spirometer.
- Repetition: The process is repeated multiple times to ensure consistency and accuracy.
- Results and Interpretation: A computerized sensor, which is part of the lung function machine, will calculate the results. These are later presented as graphs and values.
Spirometry and Asthma
- Assessing Airflow Limitation: Detects the degree of airway obstruction.
- Evaluating Bronchodilator Response: Determines improvement in airflow post-medication.
- Monitoring Progression: Tracks changes in lung function over time.
- Supporting Treatment Adjustments: Helps tailor medications based on lung function results.
Spirometry is a cornerstone in diagnosing and managing pediatric respiratory conditions, particularly Asthma. As a type of Pulmonary Function Test (PFT), it offers objective insights that guide effective treatment strategies and improve outcomes. If you suspect your child has a respiratory issue, consult a pediatric pulmonologist to explore the benefits of spirometry.
Conclusion
Spirometry services 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 spirometry equipment from Jeager (Germany). The equipment has computer animation programs or computer games to make these tests easier for children.
Children are not young adults and need special attention during the test. They needs to be encouraged in a child friendly environment. Our specifically trained Lung Function physiologist would assist the child. Dr Ankit Parakh takes special interest in getting these tests done.

Frequently Asked Questions (FAQs)
1. What is the minimum age for spirometry?
Spirometry is typically performed in children aged 5 years and older, as they can follow the necessary instructions. There might be a 10% chance that the child is not able to perform the test in the first time. In such cases we would repeat the test in the next one week. Children who are unable to perform a spirometry can now undergo an Impulse Oscillometry, which can be done from the age of 2 years.

2. Is spirometry safe for children?
Yes, spirometry is a safe, non-invasive test with no significant risks or side effects.
3. How is spirometry used to diagnose asthma?
Spirometry identifies airway obstruction and measures the improvement in airflow after using a bronchodilator, confirming asthma diagnosis.
4. How often should a child with asthma undergo spirometry?
Regular testing every 6-12 months is recommended to monitor lung function and adjust treatment as needed.
5. What should parents do to prepare their child for spirometry?
Ensure the child avoids heavy meals, vigorous exercise, and certain medications before the test, following the healthcare provider’s advice.
