The Great Gatsby, the caught wind died out about the room

I'd like to know if in this excerpt from The Great Gatsby the phrase "the caught wind died out about the room" means that the wind died out in the room or that the wind was caught in the room:

Then there was a boom as Tom Buchanan shut the rear windows and the caught wind died out about the room and the curtains and the rugs and the two young women ballooned slowly to the floor.

Thank you.
