Bedsores are preventable injuries and almost always a result of inadequate care. Also known as pressure sores or pressure ulcers, bedsores are parts of the skin that have been damaged or killed due to restricted blood flow and pressure. If a patient is left immobile in the same position for too long, pressure on the skin can lead to these painful sores.
Three contributing factors of bedsores are:
Pressure – Immobility and constant pressure can limit blood flow to certain areas of the body. Without blood flow, skin cells can’t get the oxygen and nutrients they need to remain alive. Although bedsores can affect any part of the body, they tend to develop in areas where the body is particularly bony or cartilaginous, like the heels, knees, hips, buttocks, and elbows.
Friction – When fragile skin rubs against braces, clothing, or bedding, it can result in painful sores. Friction resulting in bedsores is almost always made worse if the skin or cloth being used is damp.
Shearing – Shearing occurs when two surfaces move in the opposite direction, creating tension. If the clothing or brace remains in the same place as the body moves, it can result in a tear of the already fragile skin.
