Was Ist Ein Tourniquet?

A tourniquet is a device that is used to apply pressure to a limb or extremity in order to limit – but not stop – the flow of blood. It may be used in emergencies, in surgery, or in post-operative rehabilitation.

Why is a tourniquet placed 3 to 4?

Believe it or not, tourniquet application is one of the most important steps in proper venipuncture. You should place a tourniquet 3 to 4 in (7.6 to 10.2 cm) above the site, tying it tight enough to slow venous blood flow and loose enough not to impede arterial blood flow.

When was the tourniquet first used?

The tourniquet was first used in 200 BC and continued up to 500 A.C during Roman emperors' era (2). At that time, saving the life of soldiers or patients with ignorance of the limb was the goal and leather instruments or bronze rings were used for this purpose.
