Which stage of pressure ulcers presents with blisters on the skin?

Stage 2 pressure ulcers are characterized by the presence of blisters, which can be intact or ruptured, and may also involve a shallow opening in the skin. This stage indicates partial-thickness loss of dermis and is a clear sign of damage to the skin, commonly appearing as a shallow crater or an abrasion. The blistering nature highlights the breakdown of the skin's first layer, which distinguishes it from other stages where the depth of tissue loss varies significantly. Understanding this stage is crucial for proper assessment and treatment, as early intervention can help prevent further progression to more severe stages of pressure ulcers.
