What is a key sign of a pressure sore?

A key sign of a pressure sore is a reddened or darkened area that does not return to normal. This condition develops due to prolonged pressure on the skin, often in individuals who are immobile or have limited mobility. The skin experiences damage as the blood flow is restricted, leading to a breakdown of the skin's integrity.

When the skin becomes reddened or darkened and does not revert to its normal color, it indicates that the tissue is at risk or already damaged. This lack of normal color change suggests that the cells in that area may be compromised, which is a crucial indicator for early detection and intervention of pressure sores. Prompt attention to these areas is vital in preventing further deterioration and promoting healing.

In contrast, a bluish tint to the skin may indicate a more severe level of compromise, often associated with lack of oxygen, while a reddened area that returns to normal quickly suggests that the skin has not sustained significant damage. An area that feels warm and moist may indicate infection or inflammation, which can also be important, but it is not the primary indicator of a pressure sore. Recognizing the signs and responding early can significantly impact patient outcomes.
