• Begin CPR if necessary
• Leave embedded objects in place and place bandages around them to prevent them from moving
• Wrap the open area with plastic wrap or whatever is readily available
• If you see air bubbles in the blood or hear air coming out of the chest cavity, cover the wound with a bandage and secure it with plaster on three sides and leave the fourth side without plaster to prevent air from accumulating inside the chest
• Apply pressure to the bandage to stop the bleeding, and add more bandages if necessary
• If possible, have the victim sit or lie on the injured side if there is no sharp object embedded in it
