Canadian doctor Dr. Alain Gauthier, an anesthetist at the Perth and Smiths Falls District Hospital in Ontario, turned one hospital ventilator into a machine that can serve nine clients using do-it-yourself mechanics. Gauthier was inspired by YouTube videos created by two Detroit doctors in 2006, according to CBC News. He said he created a complex ventilator to offer people the best chance at survival. Elon Musk added to this idea by suggesting that a single computer, pump & pressure accumulator would be fine for many patients, but ideally individual valves per patient to personalize care & avoid cross-flow risk.
