Bronchiolitis is a serious condition which can suddenly deteriorate. Therefore, only the mildest cases should be managed at home or at a primary care clinic. The following children should be referred to hospital:

• Children with signs of respiratory failure (e.g. cyanosis or depressed level of consciousness)
• If there is no improvement
• Signs of pneumonia
• Oxygen saturation below 90% with oximetry (saturation monitor)
