Pressure ulcers, also known as bedsores or decubitus ulcers, are a common issue for individuals who are confined to a bed or wheelchair for extended periods of time. These ulcers progress through several stages, each with varying severity:

Stage 1 Ulcers: These are the mildest and affect the upper layer of the skin. In this stage, the wound has not yet broken through the skin. Symptoms include redness, warmth, and soreness. Treatment involves removing pressure from the area, keeping it clean, and maintaining proper nutrition. If treated early, stage 1 ulcers can heal in about 3 days.
Stage 2 Ulcers: These ulcers have a break in the top two layers of skin (epidermis and dermis). They appear as shallow, open wounds or blisters. Treatment includes wound care, relieving pressure, and maintaining hygiene.
Stage 3 Ulcers: More severe, stage 3 ulcers involve full-thickness skin loss and damage to subcutaneous tissue. They appear as deep craters and may extend into the muscle layer. Signs of infection (such as foul odor and pus) may be present. Treatment often requires debridement, infection control, and advanced wound care techniques.
Stage 4 Ulcers: The most severe, these ulcers can extend deep into muscle, bone, or supporting structures. They are characterized by extensive tissue damage, necrosis, and a high risk of infection. Surgical intervention may be necessary. Treatment is tailored to the patient’s specific needs.

Complications of pressure ulcers can be serious, including sepsis, cellulitis, osteomyelitis, and other systemic issues. Prompt treatment is crucial to prevent complications and promote healing ¹ ² ³ ⁴.
