Look online for various challenges to design and build open-source ventilators, such as this one -- https://www.agorize.com/en/challenges/code-life-challenge?t=nlalEJjOc1pDmRCro-y3JA
"The coronavirus known as COVID-19, could infect up to 70% of the population, with as many as about 10% of positive cases need ventilation.
The Montreal General Hospital Foundation , in collaboration with the Research Institute of the McGill University Health Centre (MUHC), is launching a global innovation challenge, backed by a $200,000 CAD prize, calling for teams to design a simple, low-cost, easy-to-manufacture and easy-to-maintain ventilator which could be deployed anywhere needed to save lives."
