What is the definition of eschar?

The definition of eschar is accurately described as a dry, dark scab or dead skin falling away. Eschar typically forms as a result of necrosis, which can occur in wounds, particularly those that are deep or have been exposed to certain conditions such as burns or pressure ulcers. It is comprised of coagulated proteins and dead tissue, indicating an area where healing is not taking place and can often signify a need for medical assessment and intervention to promote healing.

Healthy skin tissue, as mentioned in one of the other options, denotes intact, living tissue that is functioning normally, contrasting sharply with the concept of eschar, which consists of non-viable tissue. Inflamed skin surrounding a wound serves as a sign of the body’s inflammatory response to injury or infection, again distinct from the dead tissue that eschar represents. Lastly, tissue rich in blood supply describes areas that are likely more vital and healing, countering the definition of eschar, which indicates compromised tissue viability.

Recognizing these distinctions is essential for proper assessment and management in nursing practice, particularly for wound care.
