What does the term "wheeze" specifically refer to in respiratory assessment?

The term "wheeze" specifically refers to a high-pitched sound that occurs during expiration, often caused by the narrowing of the airways. This sound is commonly associated with conditions such as asthma, bronchitis, and other respiratory issues where airflow is restricted. Wheezing indicates turbulent airflow through constricted or obstructed air passages, leading to that characteristic whistling or squeaking sound. Recognizing wheeze during a respiratory assessment is crucial for evaluating lung function and determining the presence of underlying respiratory conditions.

In contrast, other options refer to different respiratory sounds or conditions that do not fit the definition of wheeze. For instance, low-pitched sounds might indicate different types of obstruction, while quiet breath sounds suggest normal lung function, which does not align with the diagnosis associated with wheezing.
