Sure, as a starting point why don't you start listing projects, and as I said explain why you think they don't have "promise".
You can edit your first post in this thread with a list of projects.
That's what a "planner and people organizer" does  ;D

I know nothing about ventilators or the mechanics or the fluid dynamics etc involved, no point asking me.

You are the one who has claimed they don't have promise, please explain why they don't.

Can you run that one down Art?
- Do they have a Github to evaluate?
- Is there a BOM?
- What's your judgement of it?

I don't think that project is designed to be open or collaborative outside of the partners.

Open-source hardware projects largely fail. They just don't work out I find, because the requirements, scope of work are never nailed down and the community is full of people wanting more features until the project is undoable. Trolls add the final death blow by derailing the thread into squabbling and fighting.

OP has the positive energy on a project that is quite difficult because ventilators are "mission critical" and people die when they don't work, and think about why commercial units cost $10,000-$50,000. Yes there is major fat (pun intended) due to the medical industry's markup, but in reality these machines are complicated having a zillion parts. Look at the one Trump has GM/Ventec working in, it's a literal spaceship inside.

The MIT open-souce ventilator student project, I think is silly because it has so many CNC-machined bits and relies on compressing an Ambu bag which is intended for manual use. It would get cycled 22,000 times/day and I think it would fail due to fatigue and granny would die. It has no metering and seems to use a brushed motor, so mostly a mechanical design.

Enginerding:
Sweet Dave!  It would certainly be one approach to create a rote list of all projects.  Then discard them one by one.   

Imho, that would be a Pyrrhic approach; we could do that for the next 3-7 days, and there's a good chance we'd still be empty-handed.  Technically, that search could go on continuously even after that, as new projects are touted in media.

What I'd like to do is wait until there is ~20 upvotes.  At that point, it's more likely that if someone has "hot lead" they cite it, rather than "proving a negative".  The people in this community have a nose for what'll work.

Sound good?

Agree.

Here's the Github for the project University of Florida Medical School Project I linked before.  I read the files, not much more than a theory of operation.  No BOM.
