Paul,

WE CAN ALL WORK ON IT.  THEY WILL ALL BE NEEDED.  

IF YOU THINK NY IS BAD, WAIT UNTIL IT GETS TO AFRICA's POOREST WHERE THEY DON'T EVEN HAVE HOSPITALS.

Then you must have the mechanical drawings and bill of material for the units. What else is needed?

Why are you posting in an Arduino forum?

Moved your topic to it's current location as it is more suitable.

Could you take a few moments to Learn How To Use The Forum.
Other general help and troubleshooting advice can be found here.
It will help you get the best out of the forum in the future.

Take care not to spam the forum too much as that may hinder your enthusiasm !

It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google or the fact that you gave nothing to go with in the first place so I used my wonky crystal ball.

By the time a hobbyist is done designing and testing a medical device to make it reliable enough to be used for medical device (not even considering the time it takes to move it from working prototype to mass produced product - that's going to take a lot of time and cost a lot of money) this epidemic will be long ago over. It won't last more than a few years.
Quality of answers is related to the quality of questions. Good questions will get good answers. Useless answers are a sign of a poor question.

When they have nothing at all, something is better than nothing, if they just have to let people die.

It's being controlled by an Uno.  Here's the latest update from Oxford, it look promising:

I'm sure this community can come up with multiple designs and have them produced within weeks.

When they have nothing at all, something is better than nothing
You have no idea how sick I am of seeing this phrase plastered all over the place the last few days!

No, "something" is not necessarily better than nothing. A simple example: when you are evaluating the Risk of a medical device, there are three primary targets of Harm that you need to be concerned with: Patient, Operator and Machine. Usually in that order.

If you build a "ventilator" and it disperses virus-containing particles around the room, you've just made the situation worse in that now you're causing harm to the Operator and any bystanders.

There are experienced engineers who deal with these issues every day. What makes you think that a random group of hobbyists with no knowledge of which details are important will do a better job than them?

I realize that people want to help and feel they need to do something. But sometimes the best thing to do is nothing.
Electronics and firmware/software design and assistance. No project too small

There is NO REASON it has to "disperse virus-containing particles around the room"  !

"the best thing is to do nothing"  -   REALLY?  Tell that to the person they have to let die because they don't have a ventilator for them.

There are already many people trying to do this.  If you are sick of seeing something, then don't look at it, admit you are a failure, and go post somewhere else.  

They have requirements for what they need.  5 to 20 inches of water (.2 - .75 psi) max pressure.  ~15 L air per minute, up to 20 breaths per minute.  It seems to me that if you can squeeze a Bag Valve Mask you can help.

From a recent article in the Detroit News:

"the hospital has a large number of BiPap machines that can act as ventilators. There are ventilators in the operating rooms, but those must be manually operated."
This is My Job, ER Doctor...

So yeah, they are looking into any alternative!

An example: A university DOCTOR rigged up his own BVM (Bag Valve Mask) ventilator machine:

'Going full-on MacGyver' - U of M doctor creates makeshift ventilators to battle COVID-19

But you know what, right now the doctors should be Doctoring, not Making.  Leave the Making for the experts.  Us!

It needs to be:

1.  Simple!  Have you seen what the nurses have to deal with in the ER ?!
2.  Robust!  Not Delicate in any way!  NO WEARING OUT OR BINDING OR BREAKING.
3.  Simple To Set Up and Operate!
4.  Reliable!  Over MONTHS of continuous use.
5.  Stable!  Repeatable cyclic operation continuously.  
6.  Extremely low cost!
7.  Can be produced IMMEDIATELY!
