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.

How do I use the word tourniquet in a sentence?
You've offered to apply a Band-Aid, when what I need is a tourniquet. Please don't apply a tourniquet unless you are certain that you can quickly deliver this patient to a doctor. Because direct pressure has not stopped the blood from gushing out of the wound, a tourniquet seems to be necessary.
What should you do if the combination of extremity elevation and direct pressure do not control the bleebing?
If these two actions do not control the bleeding and it is located on and extremity the use something called a tourniquet to stop all blood flow to the extremity. Please look up the proper way to use a tourniquet because if used improperly, a person could loose a limb.
Will surgical tubing work as a good tourniquet to stop bleeding?
Yes, surgical tubing will work as a tourniquet but an ER would be better. Try a direct pressure dressing first.
How do you determine the lowest effective tourniquet pressure?
When the wound is no longer bleeding, then the tourniquet is tight enough. It will need to be loosened every few minutes so as to not kill the limb it is applied to.
How do you do phlebotomy?
Phlebotomy is the act of extracting blood from humans or animals. To do it, the phlebotomist (technician) uses a needle or some kind like that. But, to start performing this job, one needs a phlebotomy certification. You can get it after passing a national exam.
What should you do if elevation of the extremity and direct pressure do not control the bleeding?
Application of pressure points well depending on the extrimity or use a tourniquet.
What should you do if the combination of extremety elevation and direct pressure do not control the bleeding?
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).
