With respect to the Red Cross, I follow the CoTCCC guidelines for traumatic injury. Their recommended devices and adjuncts (current, as far as I know) can be seen at https://books.allogy.com/web/tenant/8/books/f94aad5b-78f3-42be-b3de-8e8d63343866/. As far as I know the actual guidelines aren’t available for free on the Internet.
