Demonstrating absence of cerebral blood flow

Absence of cerebral blood flow may also be used to confirm death of the whole brain.

Although total absence of cerebral blood flow provides compelling evidence of brain death, findings can be equivocal in the presence of unequivocal clinical signs of brain death.
