what is the maximum amount of time a tourniquet should left on
You should never remove a tourniquet after it has been applied unless you are qualified in advanced medical treatment. That said, tourniquets shouldn't be applied in the first place if the bleeding can be stopped with the application of direct pressure and should only be used on the arms or legs (and below - ie. hands, feet, etc.).
what is the maximum amount of time a tourniquet should left on
no longer than one minute
2 minutes
60 seconds
for one minute
You put it on and leave it on until the person gets to the hospital.
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.
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.
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.
no longer than a minute and a half to two minutes once you get the needle into the vein you should tell the person to relax the fist first then remove the tourniquet if left on too long you can obliterate the blood supply and cause tissue damage
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.
on minutes no more than that .
Tourniquets are dangerous when used improperly, such as having them applied too long, as they restrict blood flow to the extremity or limb, therefore resulting in failure of that limb or extremity.
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!
as soon as blood is drawn from the vein the tourniquet should be immediately open from the arm. otherwise there can be obstacle in the blood flow.
