How is a stage I pressure ulcer characterized?

A stage I pressure ulcer is characterized by intact skin that displays non-blanchable redness. This indicates that there is localized inflammation that does not fade when pressure is applied and released. The non-blanchable redness suggests that there is damage occurring beneath the skin, even though the outer layer remains intact. It serves as an important indicator for the risk of further skin damage or development of deeper ulcers if preventive measures are not taken.

In contrast, blistering skin would imply a more advanced type of injury or skin breakdown that does not align with the description of a stage I ulcer. An open wound with tissue loss signifies a stage II or higher ulcer, where there is visible damage to the skin tissue. Lastly, skin that is peeling away typically suggests more complex skin integrity issues that also exceed the characteristics associated with a stage I pressure ulcer. Understanding these differentiations is crucial for accurate assessment and timely intervention in wound care.
