Diagnosing bronchiolitis

Your health care professional will ask you about your baby’s symptoms and examine their breathing.

They will listen to your baby’s chest and check their temperature.

They may also see how well your baby’s lungs are working by a test called pulse oximetry to measure how much oxygen is in the blood.

If you have concerns or need advice, call our helpline on 03000 030 555 between 9am and 5pm on a weekday or email them.

We'll take good care of your personal info and you can update the way we contact you at any time - check out our privacy policy at to find out more.
