In phlebotomy, the tourniquet should be tight enough to obstruct venous outflow, but not tight enough to obstruct arterial flow. Anything less than the systolic blood pressure is ok (i.e. will not obstruct arterial blood flow), but typically much less pressure is needed as veins are a low pressure system.

At that point, if you have not yet tied a tourniquet, tie one above the wound making sure it is tight, keep it at an elevation and keep adding direct pressure to the wound. Not much else can be done to stop bleeding. If you can see the blood vessels themselves you can use a cautery if you have one (It essentially uses heat to close off the blood vessel).
