Burn
Cool the burn with cool or lukewarm running water for 20 minutes as soon as possible after the injury. Never use ice, iced water, or any creams or greasy substances like butter. Keep yourself or the person warm. Use a blanket or layers of clothing, but avoid putting them on the injured area.
Bleeding
Press the bandage firmly with your palm to control bleeding. Apply constant pressure until the bleeding stops. Maintain pressure by binding the wound with a thick bandage or a piece of clean cloth. Don't put direct pressure on an eye injury or embedded object.
Fracture
Apply pressure to the wound with a sterile bandage, a clean cloth or a clean piece of clothing. Immobilize the injured area. Don't try to realign the bone or push a bone that's sticking out back in.
Unconsciousness
Bend the top leg so both hip and knee are at right angles. Gently tilt their head back to keep the airway open. If breathing or pulse stops at any time, roll the person onto their back and begin CPR
Cardiac Arrest
Give CPR: Push hard and fast. Push down at least two inches at a rate of 100 to 120 pushes a minute in the center of the chest, allowing the chest to come back up to its normal position after each push.
Choking
Bend the person over at the waist so that the upper body is parallel with the ground. Deliver five separate back blows between the person's shoulder blades with the heel of your hand. Give 5 abdominal thrusts. Perform five abdominal thrusts (also known as the Heimlich maneuver).
