What does ecchymosis refer to in medical terminology?

Ecchymosis is a term used in medical terminology to describe the escape of blood from blood vessels into the surrounding tissues. This results in a discoloration of the skin, which we often observe as a bruise. It occurs due to trauma, injury, or certain medical conditions that affect blood vessel integrity, allowing blood to pool in the surrounding tissue.

Understanding this term is crucial for EMTs and other medical professionals, as recognizing ecchymosis can help indicate the extent of an injury, potential internal bleeding, or the presence of certain medical conditions. Other options presented do not accurately reflect the definition of ecchymosis; instead, they pertain to different medical concepts—skin burns, wound cleaning procedures, and skin infections—each with their distinct definitions and implications in medical practice.
