Anyone who has to use a wheelchair regularly runs the risk of incurring injury from poor circulation. Kalogon believes it can mitigate this common but potentially life-threatening condition with a smart cushion that prevents any one part of the body from being compressed for too long — and it has already caught the eye of the VA.

Pressure injuries are caused when a part of the body can’t get enough blood to it and the tissue starts to die. Most people have experienced the beginnings of it, like something tightening around a finger and cutting off bloodflow, but it’s not always so external, painful, or obvious.
