Coronary and cerebral perfusion pressures generated by conventional closed chest cardiac massage are often inadequate to generate the levels of blood flow that are needed to restore cardiac function and preserve brain function. Three newer forms of applying force during cardiopulmonary resuscitation are associated with varying levels of increased coronary and cerebral blood flow in animal models and are now undergoing clinical trials. The underlying principles of abdominal compression, circumferential chest compression, and sternal force applied during chest relaxation (active decompression) suggest that these techniques may significantly improve the prognosis after cardiac arrest.
