What does "wheezing" refer to in pediatric patients?

Wheezing in pediatric patients is characterized as a high-pitched sound that occurs during breathing, particularly during expiration, and is a result of narrowed or obstructed airways. This narrowing can happen due to various conditions such as asthma, bronchitis, or other respiratory infections. When the airways are constricted, the air having difficulty passing through creates the distinctive wheezing sound, which can vary in intensity.

This manifestation is important clinically, as it serves as a symptom that indicates potential respiratory issues requiring further assessment and intervention. Understanding wheezing helps healthcare providers determine appropriate treatments and strategies to alleviate the underlying causes of airway narrowing and improve patient breathing.
