I was considering an ask HN on just this. Having an effort from makers and professionals to come up with designs for mechanical ventilators when things get dire. Now I understand jerry rigging medical devices is not advisable. But a pandemic like this may get to the point where DIY solutions may offer the solution. I heard from a general practitioner that mechanical ventilators also have fine pressure control. Which would make the whole system a lot more complex. So given that I figured the concept was to flawed. But the design by MIT doesn't have these fancy ventilator function either. So it seems a cheap, available, basic ventilator would still be valuable.
