Application of a multilayer foam with 4 flaps that can be adapted to several areas of the body (including the sacrum) and consists of: an external polyurethane film, which is impermeable to liquids and bacteria using dynamic transpiration, which can form an impenetrable barrier to protect the skin; a protective layer that shields the skin against accidental knocks and helps to spread the pressure; a highly absorbent and leak-proof layer that traps the exudate inside; a layer of hydrocellular polyurethane foam; and, finally, in contact with the skin, a perforated evenly covered layer of silicone gel adhesive. in addition to Standard preventive care

The ulcer will be classified according to the National Pressure Ulcers Advisory Panel Classification. Pressure ulcer are classified and described through the use of staging systems. Staging systems describe the extent of tissue loss and the physical appearance of the injury caused by pressure and/or shear. From stage 1 (intact skin) to Stage 4 (Full-thickness skin and tissue loss).
