door buster
n.— «I am told it is a GSW (Gun Shot Wound) chest. I alert my staff and anesthesia, check the trauma room for completeness; the trauma room is in constant readiness for such an emergency, or what we on the night shift like to refer to as a “door buster.”» —“Weekend Warrior” by Shirley Fittsgill Nurse.com Apr. 7, 2008.
