Children & Young Persons
Spirometry and FeNO patient information for children and young people referred to NICS for lung function tests.
About the Tests
Your child has been referred to NICS to have lung function tests. You will receive a text with instructions on where to come for the test.
The tests help us understand how well your child's lungs are working and can help diagnose conditions like asthma.
Important: Inhaler Information
Do not stop any medication but try to avoid taking the blue inhaler (Salbutamol) for 6 hours before the appointment.
If this is not possible, let the clinician know on arrival what time your child last took their inhaler.
What to Bring
Please ensure you have the following items for your child's appointment.
Inhalers & Spacers
Please bring all inhalers and spacers to the appointment if your child has them.
Parental Responsibility
