What stage of a pressure sore is characterized by blistered skin?

Stage 2 of a pressure sore is characterized by the presence of blistered skin. At this stage, the damage extends beyond the outer layer of the skin (epidermis) and into the underlying layer (dermis). This often results in painful blisters or shallow ulcers, which can appear as open sores or abrasions. The key aspect of Stage 2 is that it involves loss of skin integrity, leading to the emergence of blisters as the body reacts to the underlying pressure. Recognizing this stage is crucial for proper care and intervention to prevent further progression of the pressure sore, which can lead to more severe stages of tissue damage.
