Italian hospital saves Covid-19 patients lives by 3D printing valves for reanimation devices

The supply chain was broken, people and 3D printing rose to the occasion. The device in question is a Venturi valve, used for a Venturi Oxygen mask. These are low-flow masks that use the Bernoulli principle to entrain room air when pure oxygen is delivered through a small orifice, resulting in a large total flow at predictable FIO2.
