I may be completely wrong and I probably am. But, as far as I can figure a wound dressing has two primary functions.
1. to apply direct pressure on the wound to keep it from bleeding.
2 .to protect the wound from infection, and further damage.
The primary function of gauze is to absorb fluid. A Trau Medic dressing supposively absorbs a pint of blood. Do we really need to absorb all this blood or simply ensure the two primary goals?
The only thing I would use it for is wound packing such as for a severe bloody nose or seeping infection ; or cushioning a wound.
