ABSTRACT:
Presented is an apparatus operable to compress the chest of a person whose heart has stopped so as to initiate and maintain the flow of blood through the body during a cardiopulmonary resuscitation procedure. Structurally, the apparatus includes a carrying case containing a motor for driving an actuator mechanism for actuating a pair of hydraulic cylinders connected together in a "slave" arrangement. The "slave" cylinder is mounted on a platform adapted to be strapped to the chest of the victim, with the "slave" cylinder having a ram that pushes rhythmically against the sternum to squeeze the heart between the sternum and backbone of the victim. A breathing apparatus (pulmonary resuscitator) may be driven by the motor in concert with the compression function to inflate the victim's lungs with air and thus supply oxygen to the blood stream.
