How to Make a Sling for a Broken Arm
Most first aid kits contain triangular-shaped bandages to make arm slings. If an arm is broken, a sling can help by reducing movement until the victim can seek medical assistance.
How to Make a Sling
1. Place the triangular bandage underneath the injured arm with the middle point of the triangle sitting beneath the victim's elbow (think "point to the joint" to remember this).
2. Place the top end of the triangular bandage over the victim's opposite shoulder.
3. Bring the bottom end of the sling up and over the forearm and tie to the side of the victim's neck.
4. Ensure the sling is fully supporting the elbow and wrist.
5. Secure the point of the triangle with tape or a safety pin. In the event a triangular bandage is not available, you can improvise a sling with a scarf or a coat. As long as the arm is supported, it doesn't matter what material is used to make the sling.
