As a Pediatrician and Allergy Asthma Specialist, I often come across children who suffer from chronic cough, wheezing, or breathing difficulties. While these symptoms may seem minor or seasonal, they could be indicators of underlying respiratory issues. One of the most effective tools we use to evaluate lung function in such cases is a test called Spirometry.

What is Spirometry?

Spirometry is a simple, non-invasive lung function test that measures how much air your child can inhale and exhale, and how quickly they can do it. It helps us assess how well the lungs are working and detect any narrowing or obstruction in the airways — which is commonly seen in asthma, allergic bronchitis, and other chronic respiratory conditions.

In children above 5–6 years of age who can follow instructions, spirometry is a powerful diagnostic tool. It not only helps us diagnose respiratory problems early but also assists in tracking progress and response to treatment over time.

Why is Early Detection Important?

In children, respiratory issues like asthma or allergic rhinitis may go unnoticed or be mistaken for frequent colds or viral infections. This often leads to overuse of antibiotics, delayed diagnosis, and avoidable complications.

Early detection through spirometry allows us to:

• Diagnose asthma accurately
• Assess the severity of airway obstruction
• Monitor lung function regularly
• Adjust medications as needed
• Prevent long-term lung damage

As someone who practices a minimal antibiotic policy, I emphasize the importance of identifying the root cause of recurring symptoms. Spirometry helps us do just that.

How is Spirometry Performed in Children?

Many parents worry about whether their child will be able to undergo the test. The good news is that spirometry is completely safe and painless. The child is asked to take a deep breath and blow into a special mouthpiece connected to a spirometer. The machine records the amount and speed of air exhaled.

I take extra care to make the process child-friendly and ensure that the child is comfortable and understands the procedure. In some cases, we may conduct a bronchodilator reversibility test to see how lung function improves after using an inhaler — a key indicator in diagnosing asthma.

When Should You Consider Spirometry for Your Child?

If your child has any of the following, it may be time to talk to your pediatrician about spirometry:

• Repeated episodes of cough or wheezing
• Shortness of breath during play or activity
• Noisy breathing or chest tightness
• Frequent night-time coughing
• Family history of asthma or allergies

Final Thoughts

As a pediatrician and allergy specialist, I believe that early detection and timely intervention are the keys to better long-term respiratory health. Spirometry plays a crucial role in helping us understand your child’s lung function and tailor treatment accordingly. If you suspect your child may have breathing issues, don't hesitate to consult a specialist and ask about spirometry.

Your child’s lungs are precious – let’s care for them early and wisely.
