Pressure Ulcer Glossary of Terms
Pressure Ulcers - Introduction
An estimated one million people in North America have a pressure ulcer (also known as a bed sore) on any given day. When pressure to a bony part lasts for a long period, blood flow is decreased and a pressure ulcer or bed sore can form.
Watch for reddened or discolored areas over bony parts, like the tailbone, hips, heels, elbow, shoulder blade or the back of the head.
People may be at risk for pressure ulcers or have pressure ulcers if they:
  • Spend most of the time in bed, for example due to a debilitating disease
  • Spend most of the time in a chair or wheelchair
  • Are immobilized from a stroke, accident, paraplegia or quadriplegia
The risk for pressure ulcers increases with:
  • poor food intake or malnutrition
  • dry skin
  • incontinence of urine or feces (stool)
