Organis GmbH is a Swiss company, founded 2011 by experts in mechanical ventilation and mechatronics. The mission of Organis GmbH is to advance the field of medical simulation training by providing high fidelity simulators. Organis GmbH develops and manufactures its products exclusively in Switzerland for worldwide distribution. The first product is TestChest, a lung/heart simulator which is completely self-contained and reacts to treatment without operator interaction. Since TestChest is based on published physiology and pathophysiology, building intensive care and anesthesia teaching cases is now possible without in-depth knowledge of simulators.
