Are there any side effects for children undergoing pulmonary function tests?
My child is 8 years old and has been coughing frequently recently. The doctor suggested performing a pulmonary function test. I'm just worried whether this test might have any side effects or negative impacts on my child's health.
Doctor's answer (1)
In general, pulmonary function tests in children do not have obvious side effects.
Pulmonary function tests are primarily used to evaluate children's respiratory health, including indicators such as lung capacity and airflow. These tests usually involve a breathing test that requires the child to take a deep breath and then exhale as quickly as possible, which helps doctors determine whether the child's lung function is normal. During the test, children are required to perform inhalation and exhalation maneuvers according to the doctor's instructions. These maneuvers are normal physiological functions and do not produce harmful substances.
However, some children may experience symptoms such as coughing due to airway stimulation of the sensitive nerves in the throat during inhalation or exhalation. These symptoms are usually transient and do not cause long-term effects. If a child has respiratory conditions such as asthma or bronchitis, symptoms such as increased wheezing or worsening cough may occur during the test. In such cases, the doctor should be informed promptly to allow appropriate intervention.
Prior to the test, parents should ensure the child is well rested and not overly fatigued. Additionally, explaining the testing process to the child beforehand can help reduce anxiety.
