You TAPE the pads firmly to the wound and as the pad expands, it actually gets tighter on the wound as the tape soon won’t allow much more room for expansion. The clotting factors in the blood that get into the pad are further squeezed and compressed into the wound. It’s all in
the way you tape the pad...tape too loosely and you have excess bleeding, tape snugly and the pad can’t expand beyond the limits of the taping. The maxi pads are much better than continued use of a tournequet as you have directed pressure at the site.
Why not just pack the wound with Kerlix and be done with it? Why not use the right tool for the right job?
