Pressure sores are known by a number of names. In addition to pressure sore, they are sometimes called bedsores, or decubitus ulcers. Pressure sores can occur over any part of the body but, for the wheelchair-bound, the major risk areas are the ischial tuberosities and the sacrum. The consequences of developing such a pressure sore is severe and can be life threatening. The actor Christopher Reeve died due to complications from such an injury.
Pressure ulcers occur when lying or sitting in one place for too long. The skin needs blood and oxygen to get nutrients. Pressure on the skin blocks the blood supply. If the blood supply is blocked for a long time, a red area may be seen. Pressure can cause ulcers in less than two hours. If the pressure is NOT removed, the tissue in the red area will be starved of its blood supply and it will die.
Dr. Melissa Richardson of Carolina Rehabilitation Associates in Greenwood, South Carolina writes,
"For patients who require a wheelchair for mobility and sit for the majority of activities, pressure relief of the skin is essential to prevent pressure ulcers. I counsel my patients to change position in the chair at least every twenty to thirty minutes.
'Bottoms-Up' is a new device that can serve as a much needed reminder for patients to shift position. I am pleased to offer my support towards the further development and availability of this product."
