What are 3 intrinsic and 3 extrinsic factors that may contribute to pressure ulcers?

Pressure ulcers are caused by intrinsic and extrinsic factors. The intrinsic factors include immobilization, cognitive deficit, chronic illness (eg, diabetes mellitus), poor nutrition, use of steroids, and aging. There are 4 extrinsic factors that can cause these wounds—pressure, friction, humidity, and shear force.

What are 3 three intrinsic factors for pressure injury development?

Findings identified that the three main factors which contributed to PI development were reduced mobility/activity, perfusion alterations (e.g. diabetes, vascular disease, poor circulation, blood pressure changes, smoking, oedema), and skin or PI status (e.g. a history of a previous PI occurrence).

What 3 factors contribute to the development of pressure ulcers?

Pressure ulcers can be caused by: pressure from a hard surface – such as a bed or wheelchair. pressure that is placed on the skin through involuntary muscle movements – such as muscle spasms. moisture – which can break down the outer layer of the skin (epidermis)

Bedsores occur when pressure reduces or cuts off blood flow to your skin. This lack of blood flow can cause a pressure wound injury to develop in as little as two hours. Skin cells on your epidermis (your skin's outer layer) start to die. As the dead cells break down, a pressure ulcer injury forms.
