Which item in the first aid box is essential for pressure dressings?

Surgical pads are essential for creating pressure dressings due to their design and functionality. They are thick and absorbent, making them effective in controlling bleeding by applying direct pressure to a wound. When a surgical pad is placed over a bleeding site and secured with a bandage, it helps to maintain pressure that can effectively stem the flow of blood and facilitate clotting.

In contrast, while triangular bandages can be used to secure a dressing, they do not provide the necessary absorbency or pressure on their own. Adhesive bandages are more suited for small cuts and scratches and do not provide the stability or coverage needed for larger wounds. Splint padding is primarily designed to cushion and support injured limbs rather than to control bleeding. Thus, surgical pads are the most suitable choice for managing wounds that require pressure dressings.
