My husband carries a variety of bandages in the first aid bag in his truck, everything from small band-aids to giant sterile bandages and everything in between. He also has some material to form a splint, special scissors, a variety of antiseptic ointments, a mouth shield for doing mouth-to-mouth resuscitation, blankets and gloves. He used to have an IV kit and this special powder to stop bleeding, but they got too old. Most of this is stuff he was given when he took various combat lifesaver courses in the Army. And, while he has stopped at many car accidents, none of this was ever needed, thankfully. But, he assembled this kit after a man almost bled to death at a restaurant after having a heart catheterization. He was able to help the man until the ambulance arrived, but next time he will be prepared.
