Bed sore break in continuity of skin.?

Bed sores, also known as pressure ulcers or pressure injuries, are not simply breaks in the continuity of the skin. They are localised injuries to the skin and/or underlying tissue, usually over a bony prominence, as a result of pressure, shear, or friction.

Pressure ulcers can range in severity from non-blanchable erythema (stage 1) to full-thickness tissue loss (stage 4). They require prompt treatment and prevention strategies to avoid complications and further tissue damage.
