SimX’s software replaces your physical simulation mannequins with a customizable, high-definition, 3D virtual patient that can be projected onto any empty hospital bed. Whether obese, pregnant, young, old, vomiting, missing limbs, bleeding, or expressing any number of other physical signs and symptoms, SimX’s software allows you to reproduce patient presentations with unprecedented visual fidelity.


SimX allows you to access thousands of cases from top hospitals across the globe! Let your trainees learn from specialists at the cutting edge of their field. Tap into the expertise of your own simulation specialists. Market your cases to the world and turn your expertise into revenue.


SimX’s marketplace, case authoring tools, and moderator interface are all located on the cloud, so you don’t have to worry about downloads or compatibility issues. Write and run cases from your desktop, laptop, or even your mobile device! If it has a browser, it works with SimX.


SimX’s case authoring and moderating tools come with powerful reporting features built right in. Every order, request, and event is recorded on the case timeline, so your team can debrief and see how cases might have gone if their decisions had been different. Create powerful reports that can help you pinpoint where trainees need the most help, and can track the improvement of teams or individuals over time.
