What does “bay” mean in an Emergency room?

What does "bay" mean in an Emergency room?
A doctor says to a nurse,
"Get this patient to a bay, stat!"
"Put him(patient) in bay 1."

Is it a special isolated room in the ER? Or is it a small section surrounded by one of those white curtains? The picture doesn't really show what kind of a place it is, so I am not really sure how to translate the word.
Would somebody please help me with this word "bay"?
