I have used it on a variety of wounds and when placed appropriately it is a very good way to control hemorrhage temporarily. It can be used in difficult wounds and I have used it on a variety of wounds to include cardiac injury, vertebral artery injury, diaphragm, chest wall, pelvic fractures, scalp lacerations, and extremity wounds. While it is not the solution for all sources of hemorrhage, it is an extremely valuable tool for those taking care of people who have traumatic wounds.
