In a light-skinned person, what is the first sign of a pressure injury?

The first sign of a pressure injury in a light-skinned person is a reddened area. This redness occurs as a result of increased blood flow to the tissues in response to pressure, indicating that the skin and underlying tissues are beginning to be compromised. This localized area of erythema is often the earliest visible sign before any more severe damage, such as blisters or open wounds, occurs.

Recognizing this early sign is crucial because it allows for timely intervention, such as relieving pressure, which can prevent the development of more serious injuries. While blisters, drainage, and gangrene are signs of more advanced stages of pressure injuries, identifying the reddened area promptly allows healthcare providers to implement strategies to alleviate pressure and protect the skin from further damage.
