As a medical professional, I can tell you that the human brain is extremely sensitive to oxygen deprivation. **The brain can survive for up to about six minutes** after the heart stops. This is the critical timeframe within which CPR, or cardiopulmonary resuscitation, should ideally be initiated. If CPR is started within six minutes of cardiac arrest, there's a chance that the brain can withstand the lack of oxygen. However, after about six minutes without CPR, the brain cells begin to die, which can lead to severe and irreversible damage. read more >> -

After about six minutes without CPR, however, the brain begins to die.read more >>
