The PolyVent fully open-source mechanical ventilator grew out of the pandemic. It is now a classroom educational tool, and for researchers who want the right to modify and repair a ventilator for experimentation on animals and with test lungs. Every aspect of the hardware and software is licensed with free-libre licenses. We have developed two three-hour classroom modules.

The PolyVent is a mechanical ventilator for research and classroom use. It is fully open-source; it is adaptable, modifiable, and repairable. You can build your own for about $2000 in parts or order one from Public Invention for $4000. We have developed two classroom modules. Although not for use on human patients, it is a flexible, open platform for veterinary work, work with animal models, and other forms of research. It has currently been used in one classroom for 3 hours, where it scored very high engagement. This projects needs volunteers, especially embedded engineering programmers who can program an Arduino in C++ .

It is extremely modular, with over 10 GitLab modules, but you can start here:, though if you become seriously interested, please contact .

The PolyVent project was founded by Victor Suturin and Nathaniel Bechard before it became part of Public Invention. Dozens of volunteers have contributed to it, but we continue to need more (unpaid) volunteers! Public Invention is a US501c3 non-profit and does not profit from PolyVents.

The PolyVent is an affordable, open, modifiable alternative for classroom education and certain kinds of graduate-level research in pulmonology, patient-ventilator asychrony, new ventilation modes such as acoustic or percussive ventilation, etc. It is instrumented by the VentMon spirometer, which uses WiFi to publish to a public data cloud, which is very convenient for remote work, research, and classroom education.

    Public Invention recently held a board meeting, in which I mentioned that if we did not win the NSF POSE grant, the Hackaday project contest, or another grant that we applied for, we might need to mothball the project. But the board insisted I keep it open and consider more options. I told them all of our grants would be resolved, either successfully or unsuccessfully, by Dec. 1st, so we agreed to make a decision at that time.

    We have almost completed a paper we are submitting to HardwareX on the General Purpose Alarm Device (GPAD). Unfortunately, the work we are doing for NASA has been all-consuming.

    The GPAD is an example of our flexible architecture; it is interfaced with a control card that we slot in and then connect with an RJ12 jack.  It is, of course, a separate module and repo:

    Judith Weng and Nina Lahoti have been working to expand the PolyVent Freespireco ecosystem.

    Nina is improving VentDisplay with ventilator control features.

    Judith has created an accurate lung model that can model the resistance and compliance of the lung.

    Though not done, these two features work together to make the PolyVent a more valuable educational tool.

    This project has been long going. But to reach more volunteers (and to sumbit to the Save-the-world prize), we are creating a face here at Hackaday.

    We need volunteers for almost everything, but a skilled C programmer with embedded engineering experience would be highly appreciated.

I love educational platforms like PolyVent (PEP) and it is truly impressive! The hands-on approach to learning is fantastic for students. This got me thinking about how important it is to showcase these skills on a resume. If anyone needs help writing a standout resume that highlights technical abilities, I have found this professional cv writing resource from Skillroads invaluable. A well-written resume can greatly improve your job opportunities after gaining valuable knowledge from platforms like PEP.

I've been using the PolyVent Educational Platform (PEP) for a while now, and I must say it's been a game-changer for my learning journey. PEP offers a wide range of educational resources and tools that have not only enhanced my understanding of various subjects but also made the learning process incredibly enjoyable. Recently, I also read a useful conversation at about is Edubirdie legit to use for academic purposes and I was really impressed by this platform after reading people's positive thoughts about it.

I doubt that---unless you built your own, nobody else has a PolyVent. But I'm glad you are enjoying whatever it is that you are using!
