An apparatus for improving cardiopulmonary resuscitation involves use of a catheter having both an occlusion balloon and a pumping balloon. The occlusion balloon occludes the aorta such that all pumping action will be restricted to the blood vessels above the balloon occlusion. The pumping balloon is cephalad to the occlusion balloon and is preferably pumped in synchronization with external cardiocirculatory resuscitation. The pumping balloon preferably inflates fir st at the caudal end and then sequentially to the cephalad end in order to provide unidirectional cephalad pumping. Oxygen-carrying fluid may be infused through the lumen into the aorta cephalad of the pumping balloon during use. |
