Dr. Alexandra Pedersen and Dr. Tony Noble of the Arthur B McDonald Canadian Astroparticle Physics Research Institute at Queen’s University outlined the Mechanical Ventilator Milano (MVM) that a team of hundreds of physicists and engineers came together to build in response to the COVID-19 pandemic.

The added feature of the research institute’s ventilator is open access meaning no patent and any company or country can use the design free of charge.
