Emergency tourniquet
Emergency Tourniquet
An Emergency Tourniquet (pronunciation: /ˈtɔːrnɪkɪt/) is a constricting or compressing device used to control venous and arterial circulation to an extremity for a period of time. The etymology of the word tourniquet comes from the French word "tourner" which means to turn.
Usage
Emergency tourniquets are typically used in emergency situations to stop severe blood loss or prevent toxins from spreading in the body. They are often used in the military and in emergency medical services.
Types
There are several types of emergency tourniquets, including:
- Windlass Tourniquet: This type of tourniquet uses a rod or stick to twist and tighten a band around the limb.
- Pneumatic Tourniquet: This type of tourniquet uses air pressure to constrict the blood vessels.
- Elastic Tourniquet: This type of tourniquet uses an elastic band to constrict the blood vessels.
Application
The application of an emergency tourniquet should be done by a trained professional. It is typically applied above the injury site, but not on a joint. The tourniquet should be tightened until the bleeding stops.
Risks
While emergency tourniquets can be life-saving devices, they also come with risks. If left on for too long, a tourniquet can cause nerve damage, tissue death, and even loss of the limb. Therefore, it is crucial to seek medical attention as soon as possible after applying a tourniquet.
