Yes. In every hospital ER in America, how ever it's set up there are oxygen ‘’nipples’’(for lack of a better word) built into the wall which are fed by large tanks that are bought in by the kind of trucks you see transporting oxygen cylinders for welding, for industrial use, etc.

There are small oxygen tanks about three and a half feet long that are fitted to stretchers when patients are moved from the ER to say, x-ray or another part of the hospital.
There is also nitrous oxide used in the OR. The stuff comes in and out all week along with everything else any hospital uses. As I said, this bs fear mongering by the Democrats. "Running out of oxygen''. For God's Sake who ever the hospitals pr director who let that out should be fired.

For future reference, those are called stop cocks.
