Effect of the Abdominal Aortic and Junctional Tourniquet on Chest Compressions in a Swine Model of Ventricular Fibrillation

Abstract

Mortality for out-of-hospital cardiac arrest is high when traditional chest compressions are used without adjuncts. The abdominal aortic and junctional tourniquet (AAJT) is a device with a wedge-shaped air bladder that is used to occlude the aortic bifurcation. This augments blood flow to vital organs such as the heart and brain. We have previously shown that the addition of an AAJT to mechanical chest compressions leads to an increase in rate of survival in a model of traumatic cardiac arrest. This study was designed to determine if application of the AAJT would lead to more effective chest compressions as measured by improved hemodynamic parameters and an increased rate of return of spontaneous circulation (ROSC).
