An emergency head trauma bandage cap with a detachable strap system and method of use, which, when applied to the head, delivers minimal pressure to control bleeding, doesnt compromise cervical spine immobilization, allows for fast and effective application of cold packs to control intracranial/internal swelling or hot packs to prevent hypothermia in non-trauma situations, doesnt come apart during treatment and transport, and doesnt require a caregiver to re-wrap the dressing.
