The ECS provides an anatomically correct, feature-rich mannequin, which allows for the physical demonstration of various clinical signs including bleeding, breathing, blinking eyes and convulsions.  The human physiology models at the core of the ECS provide appropriate responses to treatment interventions, including airway and oxygenation management, fluid administration, defibrillation and the administration of drugs. Together, these systems deliver a realistic and objective training ground for learners to practice and perfect patient care without risk to real patients.
