Little off the mark here. The veins will occlude before the arteries.
Suspension Trauma begins (in as little as 15 minutes) due to hypoxia of the brain due to decreased venus return via the Inferior Vena Cava. This is due to pooling of blood in the legs caused by the occlusion of the Femural Veins which in turn leads to a decrease in circulating blood volume. Toxins will develop due to cell death (release of Potassium) in the lower limbs, this can be described as "Crush Syndrome" but this type of cellular destruction takes 1-2 hours to develop. At this stage things can become serious as the release of the K back into the blood stream causing Cardiac Arythmias which may lead to Cardiac Arrest. (Hyperkalemia)

This seems a little ambigious. Simply, do not allow the person to lay flat, keep them in the sitting position (conscious or unconscious) and do not allow them to walk around if conscious. If the person ha lost consciousness at any time whilst hanging or after call 000!s
