What Is A Pressure Ulcer?
Simply put, a pressure ulcer is localised damage that occurs to the skin and/or the underlying tissue caused by unrelieved pressure.
Ulcers can range from mild damage (typical you’d notice it as a red patch with breaks in the skin) to deeper damage (dark red or purple with black patches that can turn into much bigger wounds).
What Cause’s Pressure Ulcers?
There are two main causes for a pressure ulcer to develop. Either Pressure, caused by a concentration of body weight on one particular area over a period of time or something called Shearing. Shearing is caused by the skin being pulled in different/wrong/unusual directions. Actions that can cause this include (but aren’t limited to)…
- Sliding or slumping down in a chair or bed
- Sitting in a chair that’s the wrong size for you (too wide, narrow, small, high or low)
- Sliding down the bed and then pushing yourself back up
- Rubbing and or massaging certain areas
- Badly fitting clothes or shoes

How Can I Avoid A Pressure Ulcer?
- Tell your healthcare professional as soon as you notice any sore or painful patches of skin
- If possible, gently change your position as often as you can or if not ask for someone’s help to do it for you
- As we mentioned earlier, try to avoid repeated friction or shearing.
- Try to keep your heels elevated to minimise pressure damage.
- Make sure either yourself or someone else is checking your skin daily for signs of damage. (Top tip: If you’re on your own using a mirror should let you see most areas not normally visible to yourself)
- After a bath or shower don’t ruby our skin dry, gently pat it instead.
- Try to protect your skin from excessive moisture and/or dryness
- Stick to a well-balanced diet and make sure you keep yourself hydrated
- Keep the number of layers between your skin and your pressure reliving mattress/cushion to a minimum
- If you find yourself in a bed or chair for a long period try to avoid crumbs or creases in the material that could rub on your skin
- If possible, give up smoking
