What to expect from nebuliser treatment for bronchiolitis

Bronchiolitis affects the small airways, commonly in babies and young children. A clinician watches breathing effort, oxygen level, hydration and feeding before choosing treatment. A nebuliser creates a mist that the child breathes through a mask; it may not be helpful for every child, and the team may instead focus on comfort, fluids and clearing the nose.

The mask can upset a tired child at first. Keep your voice calm and follow the staff's positioning advice. The clinician may pause or change the approach if the child becomes distressed or breathing worsens.

Offer smaller, more frequent feeds if advised, keep the child upright while awake, and use saline nose drops only when recommended. Count wet nappies or note drinking and alertness so you can describe changes clearly. Do not give cough medicines or use a nebuliser at home unless specifically prescribed and explained.

Bronchiolitis can change over hours. Check breathing regularly, especially during sleep, and keep the child away from smoke. Follow the discharge plan even if the child seems briefly brighter after a treatment.

Get emergency help if the child is struggling for each breath, has pauses in breathing, blue or grey lips, is floppy or difficult to wake, or cannot feed because of breathlessness. Seek prompt review for clearly fewer wet nappies, worsening chest pulling-in, grunting, or a child who is becoming unusually sleepy.

Ask why a nebuliser is being considered, what improvement to look for, how to support feeds and sleep, which breathing signs matter most, and when to return for reassessment.
