How long can you hold your breath with 100% oxygen?
It may be possible to hold a breath for over 5 minutes by hyperventilation on 100% oxygen. The hyperventilation reduces the body’s carbon dioxide content but does not affect oxygen content much, but the Fio2 of 100 kPa considerably increases the total oxygen content.

How long can you go without oxygen without brain damage?

What happens to your brain when you stop breathing?
Even as more and more blood gets shunted to the brain, that blood is carrying less and less oxygen as the breath hold proceeds, so gradually your levels of brain oxygen begin to decline. That decline continues until, eventually, you give up. On average, brain oxygen dropped by about five percent by the time the subjects gave up.
What is the world record for non-oxygen aided breathing?
The current non-oxygen aided records stand at 11 minutes, 35 seconds for men (Stéphane Mifsud, 2009) and 8 minutes, 23 seconds for women (Natalia Molchanova, 2011). Severinsen has said that he hasn’t suffered any brain damage from his breath-holding record attempts.
