What is a key characteristic of a Stage 3 pressure injury?

A Stage 3 pressure injury is identified by full-thickness skin loss that extends into the dermis and may involve subcutaneous tissue. The critical aspect of this stage is that the injury results in a crater-like appearance where the full thickness of the skin is compromised, and it can expose the underlying fat. This level of damage indicates a significant loss of tissue integrity, making it more severe than earlier stages.

In contrast, characteristics like non-blanchable erythema typically indicate Stage 1 pressure injuries, fluid-filled blisters suggest a Stage 2 injury, and full-thickness tissue loss with exposed muscle aligns with Stage 4 injuries. This distinction is essential for proper assessment and treatment in patients at risk for pressure injuries. Understanding these stages is crucial for healthcare providers to implement appropriate care strategies and interventions.
