Which term describes difficulty breathing with a high-pitched whistling sound during expiration?

Wheezing is the term that specifically describes the difficulty in breathing accompanied by a high-pitched whistling sound, particularly noted during expiration. This sound occurs due to the narrowing of airways as a result of inflammation, bronchospasm, or obstruction, which makes it more challenging for air to flow, especially when exhaling.

This characteristic sound can often be heard in conditions such as asthma or chronic obstructive pulmonary disease (COPD), where airway constriction is a common physiological issue. The clarity in the description of wheezing as an expiratory sound differentiates it from other respiratory sounds that may occur in different contexts or conditions. Understanding wheezing is essential for recognizing and assessing respiratory distress in patients.

The other terms, while related to breathing difficulties, refer to different phenomena. Dyspnea is a general term for shortness of breath that doesn’t specify the sound. Stridor describes a high-pitched wheezing sound that occurs primarily during inhalation and is commonly associated with upper airway obstruction. Rhonchi refers to a rattling sound often associated with mucus in the larger airways and is not characterized by the same high-pitched quality as wheezing. Therefore, wheezing is the accurate term for difficulty breathing that includes a
