What can be done to reduce pressure on sores?

Identify heavy spots: Change body position regularly to avoid pressure in the same areas. Use cushioning to distribute the weight evenly and over a broader area thus reducing pressure in one small spot where sores are likely to occur. Elevate points of pressure with pillows, padding or air cushion devices. Common places are the heels, sacrum, hips and shoulder blades. Skin hygiene and proper nutrition are also vital.

Depends: Depends on where it is. For most locations, taking weight off the area and using foam cushions/pads help. For sores on the buttocks, air mattresses, frequent turning (when in bed), lying on side, donut pillows, etc. Can help. Reducing pressure is the key to preventing and treating pressure sores.
