Abstract
Abstract A hollow rubber chamber filled with a fluid and equipped with a pressure gauge, the chamber being designed for placement over the sternum of a heart victim while giving external cardiac compression as a means for restoring heart action. As force is applied to the sternum through the hollow rubber chamber, the gauge registers the amount of pressure applied and thus aids in the optimum administration of the Cardio Pulmonary Resuscitation (CPR) procedure.

Claim 1
Independent Claim
153 words
A breastplate compression aid for placement on the chest of a human victim over the victim's sternum comprising: an elongated compressible hollow member having approximately the length and shape of the sternum of an adult person, said member defining a closed hollow chamber along its length having substantially an oval cross-sectional configuration, a pressure gauge attached at one end of said member in fluid pressure contact with the hollow interior of said member, the other end of said member being provided with means for indicating the position of the base of the victim's sternum, fluid means for filling said chamber, whereby when said aid is placed on the body of a victim over the sternum with the longer dimension of said chamber co-planar with the surface of the victim's body and pressure is applied to said member, it will be transferred to the victim's sternum and a representation thereof indicated on said gauge.
