    Only air should enter the airways of the lungs. Sometimes foods, liquids, or vomited stomach contents may accidentally get into these airway. Inhaling can move these substances further into the lungs. This is called aspiration. Once the substances is in the lungs, it will cause an irritation an swelling in the lungs. This creates an opportunity for an infection to develop.
    Most people can prevent aspiration by creating a strong cough. However, some people may have impaired coughing ability. This may happen in people who are unconscious, have brain injuries or have trouble swallowing foods or liquids.
