Often include(s) undermining and tunneling. For example, “healing stage 4 pressure injury with granulation tissue over x% of the wound bed,” or another example might be a “fully epithelialized (or closed) stage 3 pressure injury.” how should the pressure injury staging classification be used? Pressure injuries are described in four stages.
The Skin May Be Painful, But It Has No Breaks Or Tears.
The skin appears reddened and does not blanch (lose color briefly when you press your finger on it then remove your finger). Epibole (rolled edges), undermining and/or tunneling often occur.

Oxygen Is Required For All Stages Of Wound Healing Thus Any Condition That Is Associated With A Low Tissue Oxygen Tension Is A Major Cause Of Pressure Ulcers.
There are currently six pressure ulcer stage classifications which are based on the anatomical depth of tissue that is visualized from the surface. Stage 1 ulcer is intact skin that has nonblanchable redness, stage 2 is partial thickness skin loss, stage 3 is full thickness skin loss, and stage 4 goes into deeper tissue such as muscle or bone. They often cause residents to suffer extreme pain, infection, invasive surgeries, or even death.
Rolled Wound Edges ( Epibole) And Eschar May Be Present.
