Leaning forward: Early arterial access promotes resuscitative endovascular balloon occlusion of the aorta utilization in battlefield casualties.

Uncontrolled noncompressible torso hemorrhage remains a leading cause of potentially preventable death on the battlefield. The utilization of resuscitative endovascular balloon occlusion of the aorta (REBOA) has gained considerable traction in civilian and military trauma care. Establishment of arterial access remains the rate-limiting step in endovascular aortic occlusion.
