Tesla engineers have made a prototype ventilator that largely uses car parts, the electric car company showed in a YouTube video Sunday.

The ventilator is controlled by the Tesla Model 3’s infotainment system computer, uses the Model 3’s touchscreen and controllers, and uses other car parts to perform oxygen and air mixing.
