During a physical exam, which respiratory finding could indicate a foreign body aspiration?

Unilateral wheezing is a key finding that can signify foreign body aspiration. When an object becomes lodged in one of the airways, it can obstruct airflow and lead to localized respiratory distress. This obstruction typically causes a distinct wheezing sound that is often heard only on the side of the body where the foreign body is lodged.

In contrast, clear lung sounds suggest open airways without obstruction, while symmetrical breath sounds indicate that both lungs are functioning normally and equally. Prolonged expiration can be indicative of conditions like asthma or COPD but is not specifically tied to foreign body aspiration. Recognizing unilateral wheezing as a possible sign of foreign body aspiration is crucial for timely diagnosis and management.
