1. A device for compressing the chest of a patient, said device comprising:
- a platform upon which a patient can rest;
a belt operably connected to the platform and adapted to extend at least partially around the chest of the patient, said belt further adapted for anterior-posterior compression of the patient;
a motor operatively connected to the belt, wherein the motor is capable of driving the belt with sufficient force such that the belt can compress the chest of the patient;
a first drive spool operatively attached to the motor and to the belt;
a second drive spool operatively attached to the motor and to the belt, wherein the first drive spool is disposed on a first side of a rolling mechanism and the second drive spool is disposed on a second side of the rolling mechanism that is opposite the first side;
a first spindle operably connected to the platform;
wherein the belt is disposed around the patient and then around the spindle; and
a bladder disposed between the belt and the patient, said bladder being filled with a pressure transmitting medium.
