This phantom has been developed to provide simulated training in FAST (Focused Assessment with Sonography for Trauma) ; an ultrasound examination directed at identifying the presence of free intraperitoneal or pericardial fluid in the traumatic patients, which allows detecting the possible cause of shocks such as mass hemothorax, intraperitoneal hemorrhage or cardiac tamponade.
