Unit U55. Undertake Agreed Pressure Area Care Knowledge Project 1.1 Describe the anatomy and physiology of the skin in relation to skin breakdown and the development of pressure sores A pressure sore is an area of skin or soft tissue damage caused by excessive or constant pressure. Pressure closes the blood vessels which supply blood to the skin and underlying tissue, causing damage to the tissues. A red area develops indicating reduced cirrculation to that area. If the pressure continues, the skin will continue to be damaged and will die, causing an ulcer or sore to develop. The resulting damage first appears on the skin surface as a red or dark patch. As the pressure sore progresses, the skin will break down to form an open sore or blisters, dead skin and ultimately infect underlying tissues, bones and joints. This type of skin damage can develop quickly in anyone with reduced mobility, such as an older people or someone confined to a bed or chair due to illness or injury, can get pressure ulcers. For those with impaired mobility or sensation, pressure sores are a major cause of hosiptalization. The skin of older people tends to be thinner and more delicate (ie like tissue paper), which means an older person has an increased risk of developing a pressure sore. Skin damage from pressure (pressure sores or ulcers) usually begins over bony prominences (any place where the bones are close to the skin surface), such as the tailbone (coccyx), sacral areas, the ischial tuberosites (the bony prominences which take your weight when you sit), shoulders or shoulder blades, the back of the head, ears, elbows, hips, knees, heels, ankles and toes are particularly at risk. 1.5 Identify a range of interventions that can reduce the risk of skin breakdown and pressure sores If a pressure sore develops, there are a variety of
