41 (Paolin), sensitivity is 53%, but the specificity is not calculated as the article is a study of consecutive 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 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. Brain death - anguish for the family 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". The value for the EEG test is reported as "53-80, 4/97". In ref. The diagnosis of brain death is primarily clinical. As noted before, brain death is the absence of brain activity, with no hope for revival – the patient is clinically dead. There are two types of death: clinical death and biological death. The clinical death of a person is the death of the brain. In a specific case, with a reasonable previous record of catastrophic brain damage and cert … 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. An evaluation for brain death should be considered in patients who have suffered a massive, irreversible brain injury of identifiable cause. A patient properly determined to be brain dead is legally and clinically dead. "You're dead when a doctor says you're dead," Bernat told Live Science. Brain death is the cessation of all brain activity, including all of the activity in the brain stem. Brain death means the person has died. A person in a vegetative state is alive and may recover to some degree, given time. 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. Clinical death typically leads to brain death, but these terms are not synonymous. 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. Prerequisites for the clinical Determination of Brain Death 4.1 The proximate cause must be known, and must be known to be irreversible.
