[spoiler]not to mention the fact that as soon as she waved off her shield, even if it held a varying air pressure than yours that she could survive in, she doomed herself. Room is normal air pressure. Bubble inside room also normal. Room's air pressure is increased significantly. Bubble somehow keeps its normal pressure. Then bubble is broken by other means. The room is going to crush whatever WAS inside the bubble because the air pressure is going to rush to equalize inside the place that had the normal air pressure. Right? So she would've gone splat...
