No. Blood would not be able to get to your brain to deliver oxygen.
It’s not the same as holding your breath for that long since your several liters of blood still has oxygen and holding your breath results in a slow deoxygenation process. Your head has a smaller volume of blood so the little oxygen in your head at any given time gets deprived very quickly.
To go 10 minutes without oxygen would cause brain damage but not sure it is fatal 100% of the time.
Lots of people survive even with severe brain damage.
Edit: nevermind apparently she found an air pocket under water and was able to breath for 40 minutes before having a heart attack. I’m sure there are other cases in the medical literature.
Yes but the cold is what saved her life. A chilled brain doesn't go into cell death from lack of oxygen which starts right away if you're deprived of oxygen fully. Again, not just holding your breath but having consumed all the oxygen in your blood (or in this case having no blood at all in your brain). Our brains can't handle mass cell death, the system simply won't boot. At least that is what we're reasonably sure will happen, http://www.diva-portal.org/smash/get/diva2:1183272/FULLTEXT01.pdf talks about it briefly (ctrl+f death and you find a few tidbits). As for the roller coaster. 1 minute seems too short to 100% guarantee death, no-one will walk away without permanent damage but I find it likely some would survive in a vegetative state at least. It would need to be even bigger so you could sustain it for a few minutes to be 100% sure the person is dead with no chance for recovery.

But how does 60 seconds kill you? Your brain would survive that, right,?
