Pressure ulcers are usually located…
Over a bony prominence
What puts someone at risk for a pressure ulcer
Impaired mobility Poor nutrition Excessive skin moisture Decreased sensory perception Advanced age Shear Friction
The scale used to assess patient risk for ulcer formation
Braden scale
The lower the number, the more at risk you are
Stage 1 pressure ulcer
Nonblanchable erythema
Stage 2 pressure ulcer
Partial thickness tissue loss involving the subcutaneous tissue
(Shallow crater in dermis, red pink wound bed with slough)
Stage 3 pressure ulcer
Full thickness loss involving the subcutaneous tissue
A hole but can’t see muscle bones or tendons
Stage 4 pressure ulcer
Full thickness loss with necrosis or damage to muscle or bone

A stage 4 pressure ulcer. There will be irreversible damage
Unstageable wound
Can’t see the depth of the wound
