Ive seen pictures of this and the electronics are breadboards ICs and jumper wires, etc... Maybe not $100, but close. I prototyped test equipment for many years. More power to them.
But don’t medical grade ventilators have the capability to be timed to the patient’s breathing rhythm and deliver appropriate air volume? Ambu bags are one size fits all.

As mentioned in the article the pressure and volume has to be carefully controlled plus it has to operate reliably for a million cycles. No way you build that for $100.
Ventilators damage the lungs. Much expertise is required to minimize this damage.
