Sand Therapeutic uses pressure map technology to identify problem areas and design the custom cushion. The P.A.S.C. uses a dynamic application of vacuum technology in a systematic way. Studies have consistently found that chair-bound patients are at a greater risk of developing pressure sores than those confined to bed 1 . Other studies have also found that for a static or conventional pressure redistribution surface, interface pressure reduction at the bony prominences of the body is a priority 2 . Initially, individual is seated on a high quality viscoelastic foam cushion.
Dynamic cycle begins thus relieving pressure at chosen pressure point.
