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.

Yes: Depends how long the brain was without oxygen - if the patient was immediately resuscitated, many of them recover completely.
