A mannequin has a torso portion with a simulated vertebral column and anatomical aortic zones for the REBOA procedure. A fluid pressure source provides a fluid to the torso portion, and a fluid collection reservoir receives fluid from the torso portion. Conduits extend between the fluid pressure source and collection reservoir. Valves associated with the conduits and the fluid pressure source and collection reservoir may be positioned to simulate injuries in the first, second and third REBOA zones. A main conduit simulates the aorta. A simulated groin portion is configured to receive a REBOA catheter. The simulated groin portion has a conduit simulating the femoral artery.
