A 49-year-old male asked:

Can the brain regenrate after cardiac arrest after 30min.?

Generally not: It depends on the specific situation, but if the brain has been deprived of oxygen for more than 12 to 14 minutes, the damage is (usually) at least partly irreversible. A relatively new technique called therapeutic hypothermia improves the statistics somewhat, but the outcomes for many patients are still poor.

Depends: It depends on several factors, not the least of which is body temperature.

A 34-year-old member asked:

Is there brain function during a cardiac arrest?

For a brief time: When the heart stops circulating blood to the brain the functions of brain cease after about 5 minutes. If CPR is performed the brain function can return. However prolonged CPR may not get enough blood to brain to prevent brain damage even if heart recovers.
