Spirometry for Children

What is Spirometry?
Spirometry is a test used to evaluate and assess lung conditions. It measures how much air you inhale and how fast you exhale. Basically, spirometry measures how well your lungs are working. The test is common and the procedure usually just takes a short period of time. It uses a spirometer which is an apparatus for measuring the volume of air inspired and expired by the lungs.


Spirometry is important for people who have asthma since the test provides information about the illness. Aside from Asthma, Spirometry is also used to diagnose lung problems or lung diseases such as:

  • Chronic Obstructive Pulmonary Disease (COPD)
  • Emphysema
  • Chronic Bronchitis

Spirometry Procedure

  • You will be seated in a chair inside your doctor’s office. Your physician or a nurse will put a clip on your nose to keep both nostrils closed.
  • The doctor will ask you to take a big breath and then blow as hard as you can on a spirometer.
  • The device will record the amount of air you breathe in and breathe out. It also measures the speed of how you breathe out.
  • The doctor may repeat the test if the results are inconsistent.

If you notice that you have a breathing disorder, it is best to take a spirometer test and learn more about the test through pulmonary doctors. The earlier you take the test, the earlier lung diseases can be detected, monitored, and treated.
