Causes of Pressure Sores

Pressure sores, also known as pressure ulcers, are caused by prolonged pressure on the skin and underlying tissues. When a person sits or lies in the same position for an extended period, the pressure restricts blood flow to the area, leading to tissue damage. Other factors that can contribute to pressure sores include friction, shear, and moisture.

Stages of Pressure Sores

Pressure sores are classified into four stages based on the severity of the tissue damage.

  • Stage 1: The skin is intact, but there is redness and warmth in the affected area.
  • Stage 2: The skin is broken, and there is a shallow open wound or blister.
  • Stage 3: The wound is deeper and extends into the underlying tissue, forming a crater-like appearance.
  • Stage 4: The wound is severe and extends through all layers of skin and tissue, exposing muscle and bone.
