Can a Three-Year-Old Child Undergo Pulmonary Function Testing?

Question

Can a three-year-old child undergo pulmonary function testing, and is it necessary to do so only when there is wheezing? Can the test be performed if there is no wheezing?

Answer

Pulmonary function testing is primarily used to identify the causes of breathing difficulties. If a child has wheezing, the test can be conducted. Ideally, it should be done during a wheezing episode, as when there is no wheezing, the results typically show normalcy and do not provide additional information. There is a possibility of asthma being genetically inherited across generations. If asthma is diagnosed, it is recommended to undergo a pulmonary function test.
