A growing body of evidence demonstrates that excursions of BP below or above the limits of cerebral blood flow autoregulation are associated with complications in patients with neurological injury or for those undergoing cardiac surgery. Moreover, recent evidence suggests that maintaining MAP above the lower limit of cerebral autoregulation during cardiopulmonary bypass reduces the frequency of postoperative delirium and is associated with improved memory 1 month after surgery. Continuous measurement of BP in relation to cerebral autoregulation limits using a virtual patient monitoring platform processing near-infrared spectroscopy digital signals offers the hope of bringing this application to the bedside.

越来越多的证据表明，血压低于或高于脑血流自动调节极限与神经损伤患者或接受心脏手术的患者的并发症有关。此外，最近的证据表明，在体外循环期间将 MAP 维持在脑自动调节下限以上可降低术后谵妄的频率，并且与术后 1 个月的记忆力改善有关。使用处理近红外光谱数字信号的虚拟患者监测平台连续测量与脑自动调节限制相关的 BP 为将这种应用带到床边提供了希望。
