One of the best inventions in peripheral IV access. Never before has a constricting IV band been so effective in contributing to successful IV attempts. Once applied to the upper extremity, the BOA®’s revolutionary patented design utilizes a rolling method which transfuses venous blood to the distal veins yet still allows arterial flow. Implementation of this rolling technique distends the veins thus making IV access quicker and more effective even in the most challenging patients. Please visit www.NARescue.com for more information.
