1. A method of compressing the chest of a patient during cardiopulmonary resuscitation, wherein the chest is characterized by the sternum of the patient and areas lateral to the sternum, said method comprising the steps of:

  • providing a device for compressing the chest of a patient, said device comprising;

    a band adapted to extend around the chest of the patient;

    a plurality of fluid receiving cells disposed along the length of the band;

    an inflation mechanism, operably connected to the fluid receiving cells, for inflating and deflating the cells to contract the band;

    a fluid-filled bladder disposed between the chest of the patient and the band, with at least a portion of said fluid-filled bladder disposed over the sternum of the patient; and

    an automated controller for controlling operation of the inflation mechanism;

    wherein the controller is programmed to control the inflation mechanism to inflate and deflate the band at a rate sufficient to perform cardiopulmonary resuscitation;

    wherein the controller is programmed to inflate the band to a tightness sufficient to perform cardiopulmonary resuscitation;

    placing the bladder on the anterior portion of the chest of the patient such that the cushion substantially covers the sternum of the patient;

    securing the band around the chest of the patient and over the bladder; and

    operating the device to inflate and deflate the band to alternately compress and release the chest of the patient in alternating compression and release phases at a rate sufficient to perform cardiopulmonary resuscitation on the patient where the compression phase achieves a tightness sufficient to perform cardiopulmonary resuscitation on the patient.
