What defines a stage 4 pressure ulcer?

A stage 4 pressure ulcer is characterized by full-thickness tissue loss, which means that the ulcer extends through the skin and underlying tissue, exposing bone, muscle, or tendon. This significant level of damage indicates the most severe stage of pressure ulcers, where there is complete tissue destruction.

Recognizing the full-thickness loss is critical for proper diagnosis and treatment, as it requires advanced care strategies to manage the wound and prevent further complications. Understanding the specific criteria for each stage helps healthcare professionals in assessing and addressing the needs of individuals at risk for or affected by pressure ulcers effectively.
