Location is everything: The hemodynamic effects of REBOA in Zone 1 versus Zone 3 of the aorta

OBJECTIVESResuscitative endovascular balloon occlusion of the aorta (REBOA) is an emerging technology to augment proximal blood pressure during the resuscitation of patients with noncompressible torso hemorrhage. Currently, placement choice, supraceliac (Zone 1) versus infrarenal (Zone 3) aorta, dep
