The first run of a new, low-cost ventilator is coming off the assembly line in New York City.
With COVID-19 raising concerns about a shortage of breathing machines for critically ill patients, the city turned to home-grown industries to try to fill in the gap.
Full-featured ventilators cost tens of thousands of dollars, but these stripped-down devices can be manufactured for a few thousand. They could be especially valuable in developing-world countries without the resources for expensive equipment.
As death rates in New York rose exponentially in March, state officials feared they would need many more ventilators. They saw what happened in Italy, where shortages forced doctors to make difficult decisions about who received access to this potentially life-saving equipment.
The federal government gave New York some assistance, but Gov. Andrew Cuomo said it fell far short.
“What are we going to do with 400 ventilators when we need 30,000?” he told reporters on March 24.
Necessity breeds invention
New York City decided to take matters into its own hands, said James Patchett, president and CEO of New York City Economic Development Corporation (NYCEDC).
“The mayor called and made it very clear that we need to focus on making ventilators and anything else we could in New York City,” he said. “The supply chain was just not reliable and that we had to do what we could to rely on New Yorkers.”
Meanwhile, executives at Newlab, a Brooklyn-based business incubator, were also watching the grim news from Italy as COVID-19 spread.
“As the virus started coming to New York, and we were faced with shuttering Newlab, I started feeling like, ‘Oh my God, we have all these talented people, and we really should do something if we can,'” Newlab co-founder Scott Cohen said.
As Cohen recovered from his own mild case of COVID-19, he came across a design for a low-cost ventilator made by MIT students 10 years ago.
Off the shelf
Cohen wasn’t alone. MIT mechanical engineering researcher Nevan Hanumara said his colleagues started hearing from a lot of people who had found the old design.
“They started emailing the former students who had been on that team, saying, ‘How can we do this? We want to know how to build this,'” he said.
The device is based around a hand-pumped piece of medical equipment known as a bag-valve mask. Viewers of TV hospital shows have seen patients wheeled into an emergency room on a stretcher with a paramedic squeezing a bag attached to their faces. That’s a bag-valve mask. Squeezing the bag draws air into and out of a patient’s lungs when they are unable to do it themselves.
The mechanical ventilator basically automates that task. But there is more to it than that. Some other designs the MIT group saw raised concerns.
“It’s not enough to make something that just punches a bag repeatedly,” said Shakti Shaligram, one of the designers of the MIT device. Too much pressure can damage the patient’s lungs, for example.
“We realized that there was a lot that was starting to pop up that would be very unsafe,” Hanumara said. “So, we reconvened and relaunched this project quickly.”
