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.
