‘急喘’ literally combines ‘急’ (urgent, rapid) and ‘喘’ (to pant or gasp), describing labored, rapid, and often distressed breathing. It is a clinical and descriptive term used primarily in medical or observational contexts to indicate breathing difficulty—such as during asthma attacks, severe allergic reactions, or acute respiratory distress. Unlike the more general verb ‘喘气’ (to breathe heavily), ‘急喘’ functions as a noun referring specifically to the *condition* or *episode* of urgent, shallow, fast breathing.

This term appears frequently in health reports, caregiver instructions, and symptom checklists. It carries a neutral-to-serious connotation and is rarely used in casual conversation unless describing a clear medical concern. While animals may also exhibit ‘急喘’, the term is overwhelmingly associated with human health contexts—especially pediatric or emergency care—where precise description of respiratory symptoms matters.
