What part of the brain dies first without oxygen?

In particular, the temporal lobe (at the temples) is sensitive to oxygen deficiency which is also where the memory is situated. A lack of oxygen from three to nine minutes can result in irreversible brain damage! In case of a cardiac arrest a CPR (Cardiopulmonary resuscitation) is best started within two minutes.

Can a person survive without oxygen for 30 minutes?

Between 30-180 seconds of oxygen deprivation, you may lose consciousness. At the one-minute mark, brain cells begin dying. At three minutes, neurons suffer more extensive damage, and lasting brain damage becomes more likely. At five minutes, death becomes imminent.

What is the difference between coma and clinical death?
