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 long do you leave a tourniquet on for?
what is the maximum amount of time a tourniquet should left on
What hospital situations is torque applied?
Torque applies to horsepower. You are thinking of tourniquet. If you lose a limb a tourniquet prevents excessive blood loss.
To stop bleeding of the arm which pressure point?
To stop severe bleeding of the arm, you should apply pressure on the brachial artery of the arm. This will reduce the flow of blood. Alternatively, a Combat Action Tourniquet may be applied to stop bleeding.
What does tiny red spots on a patients arm when the tourniquet is applied mean?

You're unable to stop severe bleeding through direct pressure what is your next step?
To stop severe bleeding of the arm, you should apply pressure on the brachial artery of the arm. This will reduce the flow of blood. Alternatively, a Combat Action Tourniquet may be applied to stop bleeding.
What should be the immidiate treatment for sever bleeding from limb?
First, try to stop the bleeding with firm, direct pressure to the wound using a clean cloth (though if the situation is severe enough, using your bare hand is better than the person bleeding out.) You may have to keep steady pressure on for fifteen minutes.If direct pressure fails to work after fifteen minutes, and you know where the vessel is is, apply pressure to the major blood vessel supplying the wounded limb. (For example, for severe bleeding in the upper leg one would apply pressure to the femoral artery for that leg, which runs close to the surface in the groin.)If direct pressure and vessel pressure both fail, a tourniquet may be applied to the limb above the wound.NEVER TIE A TOURNIQUET WITHOUT A QUICK-RELEASE METHOD.Tourniquets cut off almost ALL of the blood supply to a limb, and a knot that must be fumbled with or cut in order to restore blood flow can be the difference between saving a limb and losing it.If you are using a strip of cloth for the tourniquet, tie it more or less loosely around the affected limb, above the wound and not directly over a joint. Then slide a pencil or a stick under the cloth and turn the pencil/stick to tighten the cloth around the limb, securing the pencil/stick in place with another length of cloth.If using a rubber tourniquet band, tie a slip-knot such that the tourniquet may be released by simply tugging one of the ends.A blood pressure cuff may also be used as a tourniquet if necessary.NOTE: Leaving a tourniquet on too long can cause severe damage to the limb.ALWAYS write the EXACT time the tourniquet was applied DIRECTLY on the patient if possible, and in two places (ICUs and emergency rooms write it in indelible marker just above the tourniquet and on the patient's forehead!) Once a tourniquet has been applied, seek IMMEDIATE professional medical help by taking the patient to the nearest emergency room or by calling 911 (or the equivalent emergency number in your country) if the patient cannot be moved or if you suspect a spinal injury.
How many minutes should you wait before reapplying tourniquet?
Severe bleeding is life threatening. So, using a tourniquet to stop such bleeding may be necessary until professional help arrives. A tourniquet is very much a double edged sword. They can save a life and they can cause death. Today, the recommended way to stop bleeding, severe or otherwise, is with direct pressure on the wound. This allows blood circulation to other areas near to and downstream from the wound. The problem with a tourniquet is that it can cut off all circulation from the point of application to the end of the limb. Extended loss of circulation can cause infection, such as gangrene, and blood clots, which can result in stroke, heart attack, or lung clot. All these things can be fatal or severely disabling. A tourniquet should be used only if direct pressure cannot sufficiently control the bleeding. It should be applied and released using a regular rhythm of about 1 minute on, then 1 minute off. And, it should be used with direct pressure. Most first responders avoid using them altogether.
Why must a tourniquet be loosened from time to time?
A tourniquet must be loosened only in the event of a deep laceration. When one has been applied due to amputation, it should not be loosened. Loosening a tourniquet for a laceration, blood flow can continue continue to other tissue so that an amputation does not become necessary.
What is the preparation for venous access?
For peripheral vein access in the arm, a tourniquet is applied a few inches over the puncture site.
What is a technique used to stop bleeding that is very dangerous since it stops all flow of blood?
A tourniquet is a method of stopping bleeding that stops all blood flow.Tourniquets are what you are looking for.tourniquetA tourniquet is a constricting or compressing device used to control venous and arterial circulation to an extremity for a period of time. Pressure is applied circumferentially upon the skin and underlying tissues of a limb; this pressure is transferred to the walls of vessels, causing them to become temporarily occluded.A tourniquet.tourniquet - something that is tied around a limb to stop severe bleeding.a tourniquetYou are describing a tourniquet. Once a mainstay of every first aid course, tourniquet is now, as you say, used only as an absolute last resort. If a wound is deep enough to have cut a major artery (the wound is literally spurting jets of blood) a tourniquet is the way to go, yes. But for even a deep wound where there is no "spurting" blood, soft pack pressure compress is the preferred method.
How far above a wound should you apply a tourniquet?
I most cases a tourniquet should not be taken off once applied until the patient is in a surgical setting with a trauma physician.
