What characterizes a stage 1 pressure ulcer?

A stage 1 pressure ulcer is characterized by intact skin that may appear red and does not blanch when pressure is applied. This redness indicates that there is a level of tissue damage occurring beneath the skin, while the outer layer remains intact. The lack of blanching is significant, as it suggests that the blood flow to that area is compromised, marking the beginning stages of pressure ulcer development.

This definition aligns with the established guidelines on pressure ulcer classification, emphasizing that stage 1 pressure ulcers are still at a point where preventative actions can be taken to avoid further tissue damage. It is important to monitor the area closely for any progression or changes, as early identification is crucial in managing skin integrity and preventing more severe stages of pressure ulcers.
