Hello I'm new on the forum but I have used arduino for some simple projects the last few years.
Is there a effort to supply the world with open source life saving plans to make it possible to make a arduino based mechanical ventilator?
The forecast is there will not be enough mechanical ventilators (breathing machines) available worldwide. I think there are possibilities with arduino but I don't have enough knowledge myself. This is a chance to do something beautiful for sick people worldwide, save lives and show the amazing things people can do with arduino.
Please let me know how to get this project off the ground

... besides the little detail that you need degree in medicine and mechatronics to even get enough knowlede to get the project started. And that little pocket money ...
So arduino would take legal steps if someone makes this?
Probably not.
But the manufacturer of the MCU chip used in Arduino will not accept any responsibility for chip failure leading to injury or loss of life, and specifically forbids use of their chips in devices where failure could lead to injury or loss of life.
Any such consequences, or any consequences due to other mechanical or electrical failures in the machine you make would be entirely your responsibility.

I just want the cart to go from A to B.. i dont care about the horse.
You need to feed the horse. The problem will not be the ventilator but having enough oxygen bottles to feed them with or even just to give to those who are able to breathe on their own but need extra O2.
Also constucting the ventilator itself is likely to be a bigger challenge than controlling it.

Maybe welding oxygen.. i will first read some more about this
TheMemberFormerlyKnownAsAWOL:
...and oxygen handling is tricky and dangerous.
People breathing oxygen only consume about 1/3 of it. The other 2/3 accumulate in their clothing, bedding, and the wider room. If the patient decides to have a cigarette fires can start very easily. Just putting on an oil based ointment or cream can result in spontaneous combustion.
Flames from things burning in oxygen will be over 1000C. Patients noses, throats and lungs will of course contain high levels of oxygen and so will burn.

Do you really want to breath welding oxygen - think about it;
Firstly how clean is the inside of the cylinder.
Secondly does the compressor introduce contaminants as the tank is filled.
Thirdly how pure is the oxygen before being compressed.
Some recent discussions in theatre wondered where all the old "Bird" (pneumatic) ventilators went, and the observation that the most reliable ventilator for an infant being a mother with a bag!

I found some on eBay. $250 gets you one that is "for parts or not working", but $400 gets one "from a working environment".
The OP's heart is in the right place but amatuers manufacturing safe working ventilators in any quantity is a non-starter.
If there are any quantity of these old pneumatic ventilators around then perhaps skilled technicians could cannibalise and refurbish them.
The mother, baby, bag idea is a good one, but how long would that need to be kept up for, a week or more?
In any case at the moment healthy children under 9 don't seem to be at any risk.
