What should you know about aspiration bronchiolitis?

The inhaled material may be food, drink, saliva, vomit, or refluxed stomach contents. Symptoms can include a persistent cough, wheezing, breathlessness, and repeated chest infections. Care focuses on protecting the airway, treating any complication, and finding why aspiration is happening.

Material that enters the breathing tubes can irritate and inflame the bronchioles, the narrow airways deep within the lungs. Aspiration may occur during swallowing without an obvious choking episode, particularly when swallowing muscles or protective reflexes are impaired. Reflux, neurological conditions, reduced alertness, and structural problems affecting swallowing can contribute.

A clinician may review when coughing occurs, listen to the chest, check oxygen levels, and assess swallowing. Depending on the situation, evaluation may include chest imaging or a supervised swallowing study. These checks help distinguish ongoing aspiration from viral bronchiolitis and other causes of cough or wheeze.

Arrange a medical assessment if coughing or choking repeatedly happens with meals, the voice sounds wet after swallowing, breathing symptoms keep returning, or chest infections recur. Until assessed, follow any existing swallowing plan and keep the person upright and fully alert during meals; do not change food or drink texture without guidance from a qualified clinician.

Treatment depends on the cause. It can involve swallowing therapy, safer feeding techniques, reflux management, oral care, or changes to medicines that reduce alertness. Antibiotics are used only when a clinician identifies or strongly suspects a bacterial infection. Inhaled or nebulised medicines may help selected people with airway narrowing, but they do not remove the source of aspiration.

Call emergency services for severe breathing difficulty, blue or grey lips, inability to speak or cry normally because of breathlessness, marked drowsiness, collapse, or a suspected blocked airway. If someone is choking and cannot cough or breathe, begin the appropriate first-aid response while help is coming.

Seek prompt medical care for worsening breathlessness, rapid or laboured breathing, fever with a deteriorating general condition, new confusion, poor feeding, fewer wet nappies or reduced urination, or coughing after an aspiration event that does not settle. Babies, frail older adults, and people with swallowing or neurological problems may need earlier assessment.

Ask whether the pattern suggests swallowing difficulty or reflux, whether a speech and language or swallowing assessment is appropriate, and which meal-time precautions fit the person's needs. It is also useful to clarify which symptoms should trigger urgent review and whether any current medicine could be affecting alertness or swallowing.
