What's new in SIMVANA

Release 2.0

June 2023

New Menu Experience

We have updated SIMVANA's main menu design to make it more user-friendly and easily accessible. Our new menu system ensures that users can quickly find and access any lesson they need, allowing for a smoother and more efficient learning experience.

Updated Anesthesia Circuit

We took some time during this development cycle to overhaul the anesthesia circuit and breathing mask. Users should find it much easier to interact with the anesthesia circuit and breathing mask during mastery lesson. This update has also opened the door to more advanced functionality coming later this year. Keep an eye out for intubation lessons later this year!

Unreal Engine Update

This release includes a major update to Unreal Engine, the framework SIMVANA is built on. This update includes numerous graphics and physics updates. Users should notice improvements in graphical fidelity as well as better performance while using SIMVANA.

Bug Fixes

Ventilation lesson fixes - We made some changes to the ventilation lessons to prevent users from accidentally completing objectives if the user coughs while the user is using the breathing bag.

Updated patient response to intravenous drugs - We made some tweaks to the patient's physiological response to intravenous drugs. The patient should react more realistically to Ephedrine and Etomidate.

Release 1.6

March 2023

48 Pharmacology Mastery Lessons

This release comes with 48 pharamacology lessons that covers inhaled anesthetics, as well as cardiac and anticholinergic drugs. Lessons cover drug basics, when they are used, and a short challenge scenario to let the user administer the drugs to bring patient vitals back to normal.

Drug Administration

The operating room now includes a stock medicine cart with an assortment of drug syringes. Users can select drugs and administer them to the patient via the IV line. SIMVANA's advanced physiology simulator will accurately respond to administered drugs.

New Operating Room Tools

The operating room is now equipped with a few new tools for SIMVANA users. Reach into the wrist pocket and pull out the new stethoscope. Users can hear the patient's heartbeat when placing the stethoscope on the patient's chest.

A nerve stimulator is available on the counter of the anesthesia machine. Users can pick up the stimulator and attach it to the patient's face or wrist and observe accurate patient responses to 4 different nerve stimulator tests.

Patient Vitals Chart

The new patient vitals chart tab on the tablet automatically tracks the patient's vitals throughout the simulation (thankfully you don't have to fill it out yourself).

Conscious Patient Freeplay Mode

You can now practice an induction sequence with SIMVANA's new conscious patient freeplay mode. Users can put a patient to sleep with inhaled anesthetics.

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

July 6th, 2022

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.

Per User Licensing

SIMVANA has shifted from a hardware licensing to a user licensing model. This allows customers more freedom on where they install and use SIMVANA. Licensed users can login to any computer with SIMVANA installed and use it.

Cloud based lesson delivery

SIMVANA's learning content is now delivered from the cloud. New learning content can be added and used immediately without updating the software.

This release focuses on improving the user experience of existing SIMVANA functionality. Feedback from our beta customers have brought to light some features and interactions that needed some refinement to make them easier to use for users new to SIMVANA. In addition to UX improvements, we have made some behind the scenes changes that set the groundwork for the upcoming Learning Labs feature.

New Features

  • Improved Objective list on Tablet UI
  • Refined hint icon rendering
