wheezing

This term is primarily used in medical and clinical contexts to describe a specific type of respiratory distress. It carries a strong auditory connotation, evoking the sound of air being forced through a constricted passage. While it can be used in casual conversation to describe someone who is out of breath, its most precise application is in diagnosing conditions like asthma or bronchitis.

As a noun, the word functions as a gerund describing the phenomenon of the sound itself. When used as an adjective, it modifies the nature of the breath or cough. It is distinct from "gasping," which implies a sudden intake of air, whereas "wheezing" typically refers to the labored, whistling sound during exhalation or inhalation.
