Before we get into this: You should absolutely not be building an Arduino-based ventilator as a substitute for an actual FDA-approved medical device.
As more news comes in of medical equipment shortages and measures being taken to overcome them by companies and groups big and small, the maker community has been experimenting with ways to build their on ventilators.
YouTuber Johnny Lee came upon a novel, low-cost ventilator solution and created a video around his idea for feedback from engineers and medical professionals.
Lee realized that a CPAP machine, for people with sleep apnea, uses a blower that is simply a brushless DC motor that be driven by a standard electronic speed controller – meaning it can also be driven by an Arduino. Connecting an Arduino Nano
