What's new in SIMVANA

Release 1.5

November 10th, 2022

New Mastery Lessons

This release of SIMVANA includes 10 new mastery lessons covering Uptake & Distribution of Inhaled anesthetics.

Topics include:

  • Alveolar Concentration and Ventilation
  • Blood-Gas Partition Coefficient
  • Inspired Concentration
  • Overpressurization
  • Tissue Uptake

This set of 10 lessons is the first release of several that cover Inhaled Anesthetics. Future releases will come monthly starting in December, through early 2023.

Patient Physiology Panel


The patient physiology panel can be found in mastery lessons. This panel displays real-time metrics of the patient's physiology that are typically difficult if not impossible to measure in a real-world operating room.

Spontaneous Breathing


Students can learn to properly learn to assist ventilation with a spontaneously breathing patient. Patients will accurately respond to mistimed breathing bag interactions.

Spontaneous breathing is available in mastery lessons and in a dedicated new free-play scenario.

These metrics give students insight into how a patient’s physiology responds to their actions. Resulting in a better understanding of both what to do and why.

Other Updates

In addition to the new content and features listed above, this version of SIMVANA brings many bug fixes and minor quality-of-life improvements for users.

Limits on Patient Vitals - A scenario will end if the patient's vitals exceed safe limits

Enhanced user progression logging - SIMVANA will capture more detailed logs of user activity. Logs and user metrics will be viewable at mid-2023.

Performance improvements - Several improvements have been made to SIMVANA's rendering system to run more efficiently on all customer hardware.

Release 1.4

Instructor Camera

VR users now have more control when displaying SIMVANA on a TV. Users can position a camera in the OR so viewers have a better point of view when watching on a TV. Check out this video for more details: 


Vaporizer Refill

Vaporizers on the machine can now be refilled. Watch this video to see it in action:


Patient Monitor updates

The patient monitor has had a few bug fixes and additions for this release.

  • The monitor now displays inspiratory and expiratory % for both vaporizers at all times
  • The monitor now correctly calculates and displays inspiratory and expiratory percentages.

Reporting Portal (beta)

Users can now visit to view their progress in SIMVANA. Instructors can also view the progress of their students. This feature is in beta right now, so it may be a little rough around the edges. If you have any feedback on this feature, email us at

Framework update

SIMVANA's internal framework received a big update for this release. There aren't any user facing changes with this framework update. However, the update gives our developers access to the latest features of the framework, and resolves some internal bugs that were present in older versions.
