About this procedure
Spirometry helps assess how the airways function, including whether airflow obstruction may be present. The child breathes through a special mouthpiece while following a healthcare professional’s instructions. Reliable measurements require correct technique and repeatable attempts.
Who can complete the test?
There is no single age at which every child can reliably perform spirometry. Success depends on age, development, ability to cooperate and current health. Even a normal result does not exclude all respiratory conditions.
Preparing for spirometry
Before booking, ask about individual preparation instructions, including how prescribed inhalers should be managed; do not stop them on your own. Tell the team about acute infections, chest pain, recent procedures and anything that might affect the safety or quality of the test.
Signs and symptoms
- Persistent cough, wheeze or shortness of breath when clinically indicated.
- Suspected impairment of lung function.
- Monitoring certain chronic respiratory illnesses.
- Need to compare measurements before and after prescribed treatment.
Diagnosis and tests
The child performs several breathing manoeuvres. The operator checks trace quality and repeatability; the clinician interprets the results with the child’s age, height, symptoms and history. A bronchodilator response test may be arranged when appropriate.
Care and treatment approaches
Spirometry is an investigation, not a treatment. Its findings inform the next steps but cannot replace clinical examination or justify changing prescribed medicines without guidance.
When to seek urgent care
Spirometry is not a substitute for emergency care in severe acute breathlessness. If a child is struggling to breathe, has blue lips or altered consciousness, call 103 in Ukraine.
Frequently asked questions
Is spirometry painful?
No. It requires active breathing in and out on instruction, and a child may briefly feel tired afterwards.
At what age is spirometry possible?
What matters is the ability to perform the manoeuvre correctly; a professional determines suitability and test quality.
Does normal spirometry rule out asthma?
Not always. Findings must be considered alongside symptoms and sometimes further objective testing is necessary.
Important information
A medical consultation is needed for diagnosis and treatment recommendations.
Self-treatment can be harmful to your health.
