1.1 Describe the anatomy and physiology of the skin in relation to skin breakdown and the development of pressure sores Pressure ulcers/bed sores that are more commonly known as pressure sores are a type of injury that break down the skin and underlying tissues when a certain area of skin is placed under a lot of pressure for long or short periods of time. The most common places these occur are on the feet or bottom usually. Pressure sores can be anything from a discolouration in the skin to an open painful wound that exposes underlying muscle and tissue or even worse, bone. As we all know, a blood supply is carried through our bodies all the time and in that blood is oxygen and nutrients which are naturally there to help keep skin tissue healthy. If at any time the blood flow is disrupted and unable to reach certain areas, skin tissue will become starved of oxygen and eventually begin to break down and die, resulting in a pressure area. People with normal mobility don’t develop pressure sores as their body automatically makes hundreds of movements that prevent this from happening. A good example to use to explain this would be sleeping in bed. Although we think we are laid still, without us even realising, we move positions numerous times throughout the night because after lying in a position for so long we start to get uncomfortable. After reading up on pressure areas I have found out that some pressure areas can just be an inconvenience for some people that require minor nursing care and some can be potentially life threatening with a high risk of blood poisoning and or gangrene. Skin is the largest organ of the body, covering and protecting the entire surface of the body. The total surface area of skin is around 3000 sq inches or roughly around 19,355 sq cm depending on age, height, and body size. The skin, along with its derivatives, nails, hair, sweat glands, and sebaceous glands forms the integumentary system. Besides providing protection to the body...
