A tourniquet is a tightly applied band used to slow down or stop severe bleeding from an injury on the arms or legs. Knowing how to apply a tourniquet correctly can be life-saving in an emergency.
When Should You Use a Tourniquet?
A tourniquet should be used in cases of excessive bleeding that cannot be controlled with direct pressure. Some common situations where a tourniquet may be necessary include:
- Severe car accident injuries
- Gunshot wounds
- Deep stab wounds
- Crushed or severed limbs
Tourniquets can be especially helpful when emergency medical help is delayed for more than two hours.
When Should You Avoid Using a Tourniquet?
Avoid using a tourniquet if bleeding can be controlled by applying pressure with your hands and a cloth or bandage. Do not use a tourniquet on the head, neck, or torso wounds. In these cases, apply firm pressure to the wound and seek medical help immediately.
Step-by-Step Guide to Applying a Tourniquet
Follow these steps carefully to apply a tourniquet correctly:
1. Identify the Correct Placement
- Place the tourniquet a few inches above the wound, between the injury and the heart.
- Do not place it directly over a joint.
2. Apply the Tourniquet
- Wrap a strong bandage or cloth tightly around the limb.
- Leave extra bandage material at the ends to tie a secure knot.
3. Secure the Tourniquet
- Tie a square knot using the extra bandage material.
- Insert a stick or rod (known as a windlass) within the square knot.
- Twist the windlass until the bleeding slows or stops.
- Use tape or cloth to secure the windlass in place.
4. Monitor the Injury
- Check the wound every 10 minutes to ensure the tourniquet is effective.
- Do not loosen or remove the tourniquet—only trained medical professionals should do this.
