Kidney 30-40 minutes
Heart 1 hour
Brain death
Brain death : unaware bed sores
Brain stem death deep coma
Whole brain death
Preconditions Exclusions Brain stem reflexes
Apnea EEG Brain circulation
Diagnosis
Brain- stem reflexes
Pupillary reflext Optic <- Occulomotor Vestibulo-reflex occular -> Auditory <- Abducent Corneal reflex -> Trigeminal <- Facial Gag reflex -> Glossopharyngeal <- Vagus Dolls eye reflex - > Auditory <- Abducent
