I am not very familiar with the mechanics of neither a car nor a medical ventilator. Considering global coronavirus pandemic and shortage of medical ventilators in many countries, I saw some news suggesting that automakers are starting to manufacture medical ventilators, or the leaders of countries are requesting them to do so (e.g. here or here). So I was wondering if there is some overlap or similarity in production engineering of a car and a medical ventilator that makes automakers as the best candidate for making medical ventilators.
In other words, from an engineering viewpoint, what makes automakers suitable for engineering and manufacturing medical ventilators at this moment?
