Prisma Health, the largest nonprofit health group in South Carolina, announced Wednesday that it's developed a device that will enable one ventilator to support up to four patients being treated for the novel coronavirus.

Why it matters: Ventilators are critical in helping patients in the most severe cases of COVID-19 to breathe. But they're in short supply as demand grows, with the number of coronavirus cases increasing as U.S. testing capacity expands. The virus had killed more than 1,000 people and infected 69,000 others in the U.S. by late Wednesday.

Details: The Food and Drug Administration gave emergency use authorization for the Prisma Health 3D-printed device, called the VESper, which the firm said in a statement was developed with "material already in use for medical devices and produced at minimal cost."

What they're saying: Peter Tilkemeier, chair of medicine at Prisma Health-Upstate, said rapid rises in patients requiring machine-assisted breathing can cause an "acute shortage" of necessary equipment overnight.

  • The VESper "can be lifesaving when the number of critically ill patients requiring breathing support is greater than the number of available ventilators," he added. "A number of U.S. hospitals are likely to begin experiencing this with COVID-19."

Editor’s note: The headline has been corrected to reflect that Prisma Health created a ventilator expansion device (not a new ventilator).

Scoop: How the White House is trying to trap leakers

President Trump's chief of staff, Mark Meadows, has told several White House staffers he's fed specific nuggets of information to suspected leakers to see if they pass them on to reporters — a trap that would confirm his suspicions. "Meadows told me he was doing that," said one former White House official. "I don't know if it ever worked."

Why it matters: This hunt for leakers has put some White House staffers on edge, with multiple officials telling Axios that Meadows has been unusually vocal about his tactics. So far, he's caught only one person, for a minor leak.

11 GOP congressional nominees support QAnon conspiracy

At least 11 Republican congressional nominees have publicly supported or defended the QAnon conspiracy theory movement or some of its tenets — and more aligned with the movement may still find a way onto ballots this year.

Why it matters: Their progress shows how a fringe online forum built on unsubstantiated claims and flagged as a threat by the FBI is seeking a foothold in the U.S. political mainstream.
