**Background**: These two projects are, in our humble opinion, the closest to being actually buildable by a third party.

**Word of caution**:
* We do not believe they are ready to be built or manufactured in quantity, and have only had the lightest of testing.
* Furthermore, the COVID-19 disease requires critical care in an ICU;
* These designs may be excellent for patients with other diseases, such as acute trauma.
* However, some medical professionals assert that ventilators with more features are needed in the case of, Acute Respiratory Distress Syndrome (ARDS), a common complication of COVID-19, where patients may require ventilation for many days.
* As far as can be determined, these designs are in a poor state of readiness for multi-day treatment.
* Our analyses of these project is now badly out of date.


1. [AmboVent](https://1nn0v8ter.rocks/AmboVent-1690-108): A well-tested design by a large team from the Israeli Air Force. Definitely one to watch. This is the number one low-cost, easily built project since they released their [plans and code](https://github.com/AmboVent/AmboVent) on April 2nd!

1. [MIT E-Vent](https://e-vent.mit.edu/) -- This looks like one of the most advanced projects. Sadly it is somewhat closed at present, they do not actually offer designs, though they say they will.

1. ['Pandemic ventilator' could offer solution in potential 'worst case' coronavirus scenario](https://www.cbc.ca/news/canada/london/pandemic-ventilator-coronvirus-hospitals-1.5493830): A well-developed device reported on by Canadian Broadcasting Company. Creator (Mr. John Strupat) may open source design soon.
**Note**: This has a test-lung as part of the system, a very simple and important feature reproducible elsewhere even without this design. Nature of internal design not visible

# Resources

1. [Initiatives around the world](https://opensourceventilator.org/#initiatives) A separate list of initiatives, somewhat different than the one we maintain.

* the US will bottleneck on have enough people trained on ventilators,
* but also not have enough ventilators, or beds.
