So one of the reasons ventilators are so expensive is that they are life-saving equipment which means that tons of redundancy and reliability must be built into them. todays litigous society.

If someone dies because a home-grown one fails? Hospitals aren't going to take liability for that.

..a much more promising approach seems to be adaptors that allow ventilators to scale up to multiple patients. I think this is a much more realistic approach.
