On behalf of Nigel, Tourist, I have to say read his post again and:

"I am unable to refrain from pointing out that your quote appears to be total "

Your paper actually quotes
"In animals breathing air, Lutz observed that a minimal survival time of 25 seconds was reached on decompression to 43,000 ft or above."

I can assure you that an explosive decomp at 60k empties your lungs pretty quickly and you will not 'recover' after 3 minutes - based on a chamber run from 20k to 56k. Remember also that pax are breathing 'air' supplemented with O2, not O2.

I would, however, take issue with Nigel on the prospects of "survive for a long time on Oxy Masks at cruise altitude" since the partial pressure of oxygen at that altitude is too low to support consciousness for very long on a pax mask and hence the need to get down PDQ.
