Not a medical person here but can’t respirators be used more than once? Or do you have to throw them away after one time use? I thought it was a machine.
Yes, they are a machine, but apparently are plumbed to only service one at a time. Saw a pic where someone had rigged the output to service more than one person. A force multiplier but I'm sure the output would have to be boosted then regulated so all on the machine are getting the proper pressure.
