An emergency CPR feature is comprised of a timer and logic circuit mounted to a PC card with connections that are compatible to many existing control circuits for an adjustable hospital bed. The emergency CPR feature provides for "hands free" automatically repositioning of an adjustable hospital bed at a desired height, e.g., the full up position, with a flat mattress upon entry of a coded command by simultaneously depressing two switches, e.g., a foot and hand switch, by a trained attendant. The circuitry is contained on a single PC card which may be readily retrofit into existing adjustable hospital beds as well as incorporated into newly manufactured beds.
