Death is also an easy way to hurt your lungs. I hope nobody is dumb enough to use something like this in place of visiting a hospital, but if hospitals are overrun this is better than nothing.

Have to agree with this. Normally it would not be a good decision to use this or even advertise how to make it. These are however not normal times; more like we are at war and using combat medicine if the health system gets over run. This device needs improving and there is a fair degree of risk that it could be harmful, but a more advanced version made from easy to source parts could save many lives.

Lock down a list of concerns, max / min pressures, limits of pressure change rates, etc. Generalize the device so it can be dialed in.
If a ventilator can be powered by a brushed motor blower, this is quite doable and scaleable. There are unique opportunities to get maker grade devices enhanced and tested for production when lives are being lost. Certainly worth the effort while we sit on the sidelines.

#7If you're interested we are working on various mechanical ventilator designs which don't require actuators or electronics. There are actually devices like that in the market, you can learn more in our collaboration docs: https://docs.google.com/document/d/1R25O2mKT3TfSjXTmheGEevIk...
Edit: Another design we're considering based on an Army prototype: https://docs.google.com/document/d/1Hcuu-55q2a3_-LmBwg0uBdgM...

#8BEWARE: Even medical grade ventilator / CPAP is dangerous.
Re: Low-Cost Arduino-Based Ventilator
#9What we really need is a simple ventilator, designed by manufacturers who already know how to design and build these and produced at enormous scale using a shadow factory system similar to that developed in world war 2. In this model, the original manufacturer steps in to guide production, carry out quality control and probably supply the control electronics and software. All physical objects on which our civilisation depends are mass produced.

Cool, now how are you going to manage the countless other aspects of critical care? By the time you need a vent, you need a ton of other things as well.
