What breath sounds are often heard in children with Bronchiolitis/RSV?

In children with Bronchiolitis, particularly when caused by Respiratory Syncytial Virus (RSV), the characteristic breath sounds that are often detected include wheezes and crackles. Wheezing occurs due to the constriction and inflammation of the small airways, leading to turbulent airflow and high-pitched sounds during expiration and sometimes inspiration. Crackles, or moist sounds, may result from the presence of secretions in the airways and pulmonary edema related to infection and inflammation.

This combination of wheezes and crackles provides clinicians with critical information about the underlying pathology. These sounds reflect bronchial obstruction and the response to infection in patients suffering from viral bronchiolitis, helping guide assessment and treatment strategies. Each of these sounds indicates that the airways are narrowed or obstructed due to inflammation and secretions, a hallmark of the respiratory complications associated with RSV in young children.

Other options suggest either normal breath sounds or sounds associated with different respiratory conditions. For instance, stridor is typically associated with upper airway obstruction and is not characteristic of bronchiolitis. Rhonchi, while similar to wheezes, suggest larger airway obstruction but are less specific to the inflammatory process seen in bronchiolitis. Recognizing the correct
