According to tourniquet instructions, how far above the puncture site should the tourniquet be placed?

Explanation:
Placing the tourniquet a short distance above the puncture site creates venous pooling to make veins easier to see and feel, while still allowing arterial blood to flow to the hand. The recommended distance is about 2-4 inches (roughly 5-10 cm) above the puncture site. This keeps the area proximal enough to dilate the veins without pressing directly on the puncture site or being so far away that venous distention isn’t effectively achieved. In short, 2-4 inches above the puncture site is the practical balance for a successful venipuncture.
