The engine that powers SIMVANA

There is a lot going on under the hood of SIMVANA. Complex algorithms simulate patient physiology and machinery to create a life like virtual operating room environment. User movement and interactions are tracked to deliver an intuitive experience for all levels. A wealth of learning content is overlaid on top of the simulation to teach students within the context of an OR environment.

All of this and more make SIMVANA the most immersive and effective way to train outside of the operating room.

In Depth Simulation

The SIMVANA simulation is broken up into three primary, interdependent, modules. When running in tandem, the result is an immersive experience that allows for free exploration and experimentation in a virtual operating room.

Physiology Simulation

SIMVANA models the physiologic responses to anesthesia and user interaction based on data from peer-reviewed research so that the patient is able to respond accurately and autonomously.

Mechanical Simulation

SIMVANA does not rely on scripted scenarios or decision trees for functionality. Designed from the ground-up using the 'open-world' concepts of video game design, each component processes it's input independently and responds to the user realistically.  As components are connected together, complex simulations emerge that mimic a real-world environment.  The user is given the freedom to make independent decisions, but encounters the consequences for doing so.

User Input

Virtual reality allows users to act with greater freedom compared to desktop software. Every object in SIMVANA is physically simulated. Components can be freely connected and disconnected, or rearranged by the user to change the characteristics of the simulation.

Mastery Lessons

Learning the foundations of any subject is the most important part of any student's education. SIMVANA's mastery lessons overlay on top of the existing simulation, creating an immersive learning environment. Students are taught the basics through a mix of videos, quizzes, and interactive scenarios right in the operating room environment.

Currently, mastery lessons cover the foundational topics of the anesthesia machine. Our subject matter experts continually author and publish new mastery lessons which are available immediately within SIMVANA.

Self-Paced Learning

Learning content is only a few clicks away. SIMVANA has been designed from the ground up to support asynchronous learning. Students can run through content in class with the help of an instructor, or practice different scenarios on their own. At the end of a session, students can send usage reports to instructors or administrators.
