How long can tourniquet be left on arm for blood draw?

How long do you keep a tourniquet on?
A tourniquet should not be removed at all. Tourniquets are a LAST RESORT method. They are hard to apply, they cause a lot of pain, and they can lead to the loss of any limb below wherever the tourniquet was applied. However, if the choice is your LIFE or your LIMB, choose the life. Apply the tourniquet and tighten it until the bleeding stops. Secure the stick to make sure the tourniquet does not loosen and DO NOT TOUCH IT. Get the victim to a hospital immediately. Once there, the doctors and nurses are trained in how to remove tourniquets and treat the wounds. If you leave a tourniquet on too long, the person might lose their arm/leg/whatever. If you take it off too soon, they can easily bleed to death.

How come that when you put a tourniquet on the arm it becomes gangrened?
When a tourniquet is left on for too long, it restricts blood flow to the body part beyond it. This lack of blood flow can lead to tissue damage, cell death, and ultimately gangrene due to lack of oxygen and nutrients. It is important to use a tourniquet properly and not leave it on for an extended period of time to avoid this complication.

How long should a tourniquet be left on a pt arm during venipuncture procedure?
how long should a tourniquet stay on a patients arm:There is no clearcut rule as to how long a tourniquet may be inflated safely, although various investigators have addressed effects of ischemia on muscle and nerve to define a relatively "safe" period of tourniquet hemostasis. In practice, safe tourniquet inflation time depends greatly on the patient's anatomy, age, physical status, and the vascular supply to the extremity. Unless instructed otherwise, report to the surgeon when 60 minutes of tourniquet time has elapsed. There is general agreement that for reasonably healthy adults, 90 minutes should not be exceeded without releasing the tourniquet for a short time.
