Let looks on how the pressure is develop into the clinical condition. Pressure ulcers develop because of the weight of the body giving a pressure toward the skin. The pressure disrupt the blood flow to the affected area of the skin. This disease usually occur where the bone is close to skin (Bony prominence) is pressured against a surface such as floor, a chair or even a bed. The compression toward the skin and the underlying tissue causes the blood vessel to damage. Even when less pressure is applied but in long period of time, the pressure ulcer also can be develop. According to (Newson, 2015), she said that rubbing or friction can also form the pressure ulcer. When we spent a lot of times on a chair or in bed, we may slide down or pulled …show more content…
Take an example, when we are sleeping we may think that we do not move but eventually we change our position a lot of times in a night.
If the blood vessel is damaged and the supply of oxygen and other nutrients are disturbed, so the skin will not receive any longer white blood cells. Once the ulcers is develop, the area of the skin will become infected because of the lack of white blood cell to kill the bacteria. Figure 4 Stages of Pressure Sores

The pressure ulcer can be divided into four stages based on their severity. At the beginning stage of the pressure ulcers or also known as stage 1 has the following characteristic such as the wound on the skin is not open and the reddening o the skin on the people who have light tone skin color and when touched, the skin does not blach. People who have darken tone skin color may have discoloration. The infected area of the skin may be tender, painful, firm, soft, warm, or cool compared with other area. “For Grade 1, nonblanchable erythema of intact skin, discoloration of the skin, warmth, edema, and hardness may be used as signs, particularly on individuals with darker skin.” (Hughes, 2008) Figure 5 Stage 1 of Pressure

The outer layer of skin also known as epidermis and the underlying layer of the skin known as dermis is damaged or lost because of the lack of white blood cell to kill the bacteria leading to skin loss. The infected area become reddish or pinkish.
“For Grade 2, indicators include partial thickness skin loss involving epidermis, dermis, or both. The ulcer is superficial and presents clinically as an abrasion or blister” (Hughes, 2008) Figure 6 Stage 2 of pressure ulcer
The third stage of the pressure ulcer occur when the ulcer become a deep wound. The skin loses their entire thickness of the skin and the infected area usually exposes some of the fat. Although the underlying tissue called dermis is damaged, the muscle and bone are not damage at all. There are some yellowish dead tissue that can be clearly seen at the bottom of the wound. The wound would look like a large cavity structure.
“Grade 3 includes full thickness skin loss involving damage to or necrosis of subcutaneous tissue that may extend down to, but not through, underlying fascia” (Hughes, 2008) Figure 7 Stage 3 of pressure
