Pressure ulcers, also known as bedsores, occur due to prolonged pressure on the skin. Improved positioning is vital in pressure ulcer prevention by redistributing weight and reducing pressure on bony prominences such as the heels, sacrum, and elbows. Regularly changing a patient's position, using pressure-relieving devices like foam mattresses or cushions, and ensuring skin remains dry and clean are critical strategies to prevent these painful and potentially serious injuries.
