How would you treat someone who was bleeding severely?
Your main aim is to stem the flow of blood. If you have disposable gloves available, use them. It is important to reduce the risk of cross-infection.
1. Check whether there is an object embedded in the wound*.
2. If there is nothing embedded, press on the wound with your hand, ideally over a clean pad, and secure with a bandage.
3. If the wound is on an arm or leg raise the injured limb above the level of the heart.
*If you suspect there is something embedded, take care not to press on the object. Instead press firmly on either side of the object and build up padding around it before bandaging to avoid putting pressure on the object itself.
