absence of clinical brain function when the proximate cause is known and demonstrably irreversible 1) clinical or neuroimaging evidence of an acute CNS catastrophe that is compatible with the clinical diagnosis of brain death 2) exclusion of complicating medical conditions that may confound clinical A coma is an “eyes-closed, depressed consciousness from which they cannot be aroused,” but there are “purposeful” brain stem responses and spontaneous (natural) breathing. 41 (Paolin), sensitivity is 53%, but the specificity is not calculated as the article is a study of consecutive There are two types of death: clinical death and biological death. As noted before, brain death is the absence of brain activity, with no hope for revival – the patient is clinically dead. The value for the EEG test is reported as "53-80, 4/97". In ref. There must be clinical or neuro-imaging evidence of an acute central nervous system catastrophe that is compatible with the clinical diagnosis of death by brain criteria. There is a fairly general consensus in western medicine on the necessary criteria and the mode of proceeding for a correct diagnosis of "brain death". A patient properly determined to be brain dead is legally and clinically dead. Clinical death typically leads to brain death, but these terms are not synonymous. An evaluation for brain death should be considered in patients who have suffered a massive, irreversible brain injury of identifiable cause. The clinical death of a person is the death of the brain. The diagnosis of brain death is primarily clinical. Brain death means the person has died. A persistent vegetative state means the person has lost higher brain functions, but their undamaged brain stem still allows essential functions like heart rate and respiration to continue. Brain death - anguish for the family Prerequisites for the clinical Determination of Brain Death 4.1 The proximate cause must be known, and must be known to be irreversible. The death of brain cells in clinical conditions is recorded after the patient leaves this state - with a working heart and breathing with the aid of an artificial lung ventilation device. Brain death is the cessation of all brain activity, including all of the activity in the brain stem. In a specific case, with a reasonable previous record of catastrophic brain damage and cert … "You're dead when a doctor says you're dead," Bernat told Live Science. A person in a vegetative state is alive and may recover to some degree, given time.
