AMHERST — The U.S. Food and Drug Administration announced that the Mechanical Ventilator Milano (MVM) is safe for use in the U.S. under the FDA’s emergency-use authorization, which helps support public health during the current COVID-19 pandemic.
An international team of physicists and engineers, including physicist Andrea Pocar at UMass Amherst, brought a simplified ventilator from concept to approval in just six weeks, from March 19 to May 1. It was conceived by physicist Cristian Galbiati of Princeton University and the Gran Sasso Science Institute in L’Aquila, Italy, who was in Italy when the pandemic hit that country.
Galbiati, Pocar’s long-time friend and fellow researcher on the DarkSide-20k project recalls, “the sense of crisis was palpable. It was clear that many patients would need respiratory assistance.”
Moved to help, Galbiati reached out to fellow researchers from the DarkSide-20k dark-matter experiment to develop a ventilator with minimal components that could be quickly produced using commonly available parts. Dark-matter researchers have extensive experience designing and using sophisticated gas-handling systems and complex control systems, the same capabilities required for mechanical ventilators.
Pocar noted that particle physicists “build our own stuff, one-of-a-kind instruments, and we have experience in developing unique electronics and software for our experiments.”
Soon engineers and physicists in nine countries, particularly in Italy, the U.S., and Canada, jumped in to help. Steve Brice, the head of the U.S. Department of Energy’s Fermilab Neutrino Division, noted that “there’s a huge benefit we’ve gained from the way particle-physics collaborations work. The structure already in place has large, international, multi-disciplinary groups. We can retask that structure to work on something different, and you can move much more quickly.”
The MVM is inspired by the Manley ventilator built in the 1960s. Its design is simple, cheap, compact, and requires only compressed oxygen or medical air and a source of electrical power. The team updated the electronics and control system. Stephen Pordes, a member of DarkSide stationed at the European Organization for Nuclear Research (CERN), noted that “we’re concentrating on the software and letting the hardware be as minimal as it can be.”
The team also worked with doctors, medical-device manufacturers, and regulators to make sure they were making something valuable and easy for medical staff to use, with a robust supply chain, and which could be quickly produced. Doctors tested the MVM prototypes on breathing simulators. Anesthesiologists from COVID-19 wards in a hard-hit region in Italy also offered detailed guidance on the design, the MVM team reported.
“MVM demonstrates that international cooperation that advances intellectual and technological innovation is possible not only in the academic arena, but also in areas where basic research impacts society and political decisions,” Pocar said, adding that the next step will be to facilitate the development of devices based on the open-source MVM in other countries, and to “try to facilitate as much as possible the seeding of entrepreneurship around this device. The intellectual property behind it would come for free for whoever wants to use it.”
