Also, every single Ventilator OEM has tons of spare parts to repair and maintain their product. That said, they do not have every single component lying around to assemble vents completely.

Think about a car or truck. They have a gazillion spare parts for repairs and such.
Build a complete car with those spares? Not a chance.

Medical devices are the same way.

If an F1 company or GMC or Ford can assist with building additional spares while OEM focuses on the items missing, then good. Press on.

But to say F1 or any other car company is going to build a vent from scratch is absurd.
