Magnetic Resonance Imaging malfunction...?
I volunteer at a hospital and the MRI machine went down the other day. They told me that when it malfunctions it sucks all of the air/oxygen/i dont know out of the air and the patient and doctor have to get out of the room in a certain amount of time. I was wondering how this is happens.

What they are referring to is the fact that all instruments that involve magnetic resonance use a combination of liquid Helium and liquid Nitrogen (in separate chambers) to cool the coils and to stabilize the magnet.
Should the instrument malfunction by what is called a "cold quench" it is probably due to or immediately preceding a loss of either or both of the gases that these coolants would release. Either of them in a confined space (e.g. a 10 x 14 ft or so room) cause a suffocating situation (displaces the oxygen); it is recommended that the occupants of that room vacate it as soon as possible

I have never heard of anything like that. MRI machines operate based on magnetism, not on vacuum principles.
