Stage 1 pressure ulcers are early-onset, non-blanchable skin lesions caused by tissue damage due to constant pressure on an area of the body. These ulcers are typically red in color, but may also present with darker hues such as purple or blue. The area may also feel warm or hard to the touch. Stage 1 ulcers often form in areas of bony prominence, such as the tailbone, heels, or hips, and can be prevented with proper positioning and padding.
Stage 2 pressure ulcers are more serious than Stage 1 ulcers and require immediate treatment. These ulcers are typically open wounds that form in areas of bony prominence and can be caused by prolonged pressure on the skin. Stage 2 ulcers may present with red, purple, or black discoloration, and may have shallow or deep tissue loss. These ulcers often form in the same areas as Stage 1 ulcers, and may be accompanied by a foul odor due to the presence of dead tissue or infection. Treatment typically includes off-loading the area of pressure, wound care, and antibiotics to prevent or treat infection.
