Revisiting the promise, practice and progress of resuscitative endovascular balloon occlusion of the aorta.

Better understanding of cardiac shock physiology provides a new lens in which to evaluate REBOA through. Patient selection remains a huge challenge.

The use of REBOA should not delay definitive haemorrhage control in those patients without impending cardiac arrest.
