For cerebral death to occur there must be many levels of cerebral function destroyed. Cortical and subcortical irreversible damage is evident by unresponsiveness to any stimuli. Brain stem and basal ganglia damage is indicated by absence of spontaneous respirations, cephalic reflexes, and thus cerebral circulation. All elements of the criteria for cerebral death must be met. The decision should be made by the attending physician in consultation with his peers. The life support mechanisms should be discontinued after the diagnosis of cerebral death has been made. Absence of pulsatile echoes means absence of cerebral circulation and cerebral function, or a definitive diagnosis of cerebral death. It is a final parameter in the criteria and allows definite measures to be taken. But it behooves one to remember that this phenomenon of cerebral death makes organ donation and transplantation possible. It has not been created in order to supply the needs for organ transplant!
脑死亡的发生必须有多个层次的脑功能遭到破坏。对任何刺激均无反应表明皮质和皮质下存在不可逆损伤。脑干和基底神经节受损表现为无自主呼吸、头部反射消失，进而脑循环停止。脑死亡的所有标准要素都必须满足。该决定应由主治医生与同行协商后做出。在做出脑死亡诊断后，应停止生命维持机制。无搏动回声意味着脑循环和脑功能缺失，即脑死亡的明确诊断。这是标准中的最终参数，可据此采取明确措施。但必须记住，脑死亡这一现象使得器官捐赠和移植成为可能。设立这一概念并非是为了满足器官移植的需求！
