Pressure Injury - 🧠ANSWER ✔✔localized damage to the skin and
underlying soft tissue usually over a bony prominence or related to a
medical or other device.
The injury can present as intact skin or an open ulcer and may be painful.
The injury occurs as a result of intense and/or prolonged pressure or
pressure in combination with shear. The tolerance of soft tissue for
pressure and shear may also be affected by microclimate, nutrition,
perfusion, co-morbidities and condition of the soft tissue.
Pressure - 🧠ANSWER ✔✔Pressure is the force (per unit area) exerted
perpendicular to the skin surface. Pressure damages the skin and
underlying tissues by
(1) directly deforming and damaging tissue;

, (2) compressing small blood vessels hindering blood flow and nutrient
supply and
(3) through ischemia-reperfusion injury. When pressure is redistributed
over a greater surface area, the pressure is less intense in any one area.
Shear stress - 🧠ANSWER ✔✔Shear stress is the force (per unit area)
exerted parallel to the tissue.
Shear strain - 🧠ANSWER ✔✔Shear strain is the actual distortion or
deformation of tissue as a result of shear stress. Some shear strain occurs
at rest. Shear strain is intensified in certain clinical situations (e.g., raising
the head of the bed > 30 degrees; dragging rather than lifting while
repositioning). One layer of tissue slides over another deforming adipose
and muscle tissue and disrupting blood flow.
Stage 1 Pressure Injury - 🧠ANSWER ✔✔Intact skin with a localized area of
non-blanchable erythema, which may appear differently in darkly
pigmented skin. Presence of blanchable erythema or changes in sensation,
temperature, or firmness may precede visual changes. Color changes do
not include purple or maroon discoloration; these may indicate deep tissue
pressure injury.
