Bandaging and dressing wounds is important for first aid to control bleeding, absorb fluids, and prevent infection. There are different types of bandages and techniques used depending on the situation. Sterile gauze pads, adhesive tapes, roller bandages, and triangular bandages are common supplies used to bandage wounds. Proper bandaging involves cleaning the wound, applying pressure to control bleeding, and securely wrapping the bandage around the injured area. Transporting an injured victim carefully is also important when further medical help is needed.
