Boy, did I ever goof! And to think I used to teach chemistry! The expansion
factor from helium liquid to gas is 700 to 750 depending on what you expect
the post-quench room temperature to be.
This leads to asphyxia onset shortly after the beginning of a quench and
near certainty of asphyxiation if anything (like a fall from a ladder due
to fear or unconsciousness) impeded your flight from the NMR lab.
The correct info is at

Feel free to link to it or clone it for your own use. Thanks to those who
reminded me about PV=nRT. Duh!
