Abstract: A disposable external cardiac compression device is provided for use in a CPR technique. The device has a height equal to the minimum depth recommended for cardiac compression and comprises a rectangular elongated main body portion of unyielding foam plastic and top and bottom cushion-like foam layers secured thereof. The bottom layer extends longitudinally beyond the main body portion to form flexible locator flanges having a length equal to the width of two fingers for properly locating the device on the sternum of a patient. The top surface has a length and width sufficient to conformably accommodate engagement by the heel of a rescuer's hand placed thereon. The locator flanges have sufficient flexibility to permit ready yielding upon application of pressure against the top surface of the main body portion and the continuous bottom surface has an adhesive for removably adhering the device to the patient.
