KED meaning in Medical ?

A Kendrick extrication device (KED) is a device used in extrication of victims of traffic collisions from motor vehicles. Commonly carried on ambulances, a KED is typically used by an emergency medical technician, paramedic, or another first responder. It was originally designed for extrication of race car drivers. Typically used in conjunction with a cervical collar, a KED is a semi-rigid brace that secures the head, neck and torso in an anatomically neutral position. Its use is claimed to reduce the possibility of additional injuries to these regions during extrication, although its value has been questioned, as there is a lack of evidence to support its use. The original KED was designed by Richard Kendrick in 1978.
