Would the Riester ri-clip Tourniquet for Blood Stasis make a good Tourniquet in a emergency first aid situation?
It would. Remember, almost anything that can cut off blood flow will make a good tourniquet in an emergency. Just don't leave it on too long.
Does leaving a tourniquet on too long cause hemolysis?
yes! your specimen will be hemoconcentrated! if you have a long draw, just lift up on the tourniquet every now and then...the blood flow will be much better, and the specimen shouldn't get hemolysized!
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.
What is the maximum leght of time for a tourniquet should be in place before blood is drawn?

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.
What happens when a tourniquet is left on too long during a venepuncture?
it causes a hematoma. Yes it does, but it also causes hemoconcentration & hemolysis.If a tourniquet is at high enough pressure and left on long enough, the tissues distal to the tourniquet may develop ischemia and gangrene, resulting in loss of those tissues.
During the venipuncture procedure the tourniquet should not remain on the patient's arm for more than how long?
According to CLSI the tourniquet should not be left on for more than a minute. If a suitable vein has not been found, remove the tourniquet, leave it off for two minutes, then reapply the tourniquet to look for suitable veins and/or perform the venipuncture.
