No existing device for cardiopulmonary resuscitation (CPR) is designed to exploit both the ‘cardiac pump’ and the ‘thoracic pump’ effect simultaneously. The purpose of this study was to measure the haemodynamic effect of a new simultaneous sternothoracic cardiopulmonary resuscitation (SST-CPR) device that could compress the sternum and constrict the thoracic cavity simultaneously in a canine cardiac arrest model. After 4 min of ventricular fibrillation, 24 mongrel dogs were randomized to receive standard CPR ( n=12) or SST-CPR ( n=12). SST-CPR generated a new pattern of the aortic pressure curve presumed to be the result of both sternal compression and thoracic constriction. SST-CPR resulted in significantly higher mean arterial pressure than standard CPR (68.9±16.1 vs. 30.5±10.0 mmHg, P
