Only 4 adult ICU beds left in Idaho: Governor
Idaho only has four adult ICU beds available in the state, Gov. Brad Little said Tuesday.
The governor said he toured a nearly-full ICU in Boise where everyone was unvaccinated.
"What I saw was heartbreaking," Little said at a news conference. "I was told the average age of the patients was 43. All of them were struggling to breathe and most were only breathing with the help of a machine. Doctors, nurses and associated medical staff are exhausted."
The governor said up to 370 additional staff, including up to 150 National Guardsmen, will be deployed to help short-staffed hospitals manage the surge.
