Information about Tourniquet
For other uses, see .
A tourniquet can be defined as 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.[1]
- Surgical tourniquets enable surgeons to work in a bloodless operative field
- Emergency tourniquets are used in Emergency bleeding control to prevent severe blood loss from limb trauma.
