Pressure ulcers, decubitus ulcers, or bedsores are injuries to the skin and underlying tissue that can develop over hours or even days. These ulcers occur when bony areas of the body have prolonged contact with an external surface, such as a bed, causing pressure and decreased blood flow to the area, leading to necrosis of the skin. Even though pressure ulcers are adverse events that are considered avoidable or preventable, they continue to be a problem. ViSi Mobile can help.
