Six key points to consider when applying a tourniquet include the application location, appropriate tightness, duration, tourniquet removal, use of padding, and record keeping. These details are as follows:
1. Application Location: The upper tourniquet is typically applied to the limbs, such as the upper third of the arm or the junction of the middle and lower thirds of the thigh. Choosing the right location will protect the limb.
2. Padding: When applying a tourniquet, place one or two layers of cloth under the application area. Do not use rope, wire, or other similar materials to avoid damaging soft tissue.
3. Appropriate Tightness: The tourniquet must be applied at an appropriate tightness. A tourniquet that is too loose may not stop bleeding, while a tourniquet that is too tight may cause local soft tissue damage. Generally, the tightness should be sufficient to stop bleeding.
4. Duration: Tourniquets should be applied for a short time, typically around one hour, and preferably no longer than three hours. Extended application can damage soft tissue.
5. Tourniquet Removal: If the bleeding has stopped after oral medication, blood transfusion, or intravenous fluid administration, the tourniquet should be removed.
6. Keeping Records: After applying a tourniquet, note the time and location of application.
