Pressure ulcers are also known as pressure sores, pressure injuries or bed sores.
They are an injury that affects areas of the skin and underlying tissue. They are caused when the affected area of the skin is placed under too much pressure which restricts blood flow to the tissue.
Skin can also become damaged by repeated friction of the skin rubbing against another surface, which is called shear.
If care isn’t taken to protect the skin, then pressure injuries can become really dangerous! The wounds can be large, painful and take a considerable amount of time to heal, they also can become easily infected.
The use of an appropriate cushion & backrest can help lower the risk of pressure injuries occurring
