The first aim was to investigate the combined effect of insult intensity and duration of the pressure reactivity index (PRx) and deviation from the autoregulatory cerebral perfusion pressure target (∆CPPopt = actual CPP - optimal CPP [CPPopt]) on outcome in traumatic brain injury. The second aim was to determine if PRx influenced the association between intracranial pressure (ICP), CPP, and ∆CPPopt with outcome.

创伤性脑损伤中脑压自动调节损伤的可视化。

第一个目的是研究压力反应指数 (PRx) 的损伤强度和持续时间以及与自动调节脑灌注压目标的偏差 (ΔCPPopt = 实际 CPP - 最佳 CPP [CPPopt]) 对创伤性脑损伤结果的综合影响。第二个目的是确定 PRx 是否影响颅内压 (ICP)、CPP 和 ΔCPPopt 与结果之间的关联。
