既往的研究表明,脑灌注压(CPP)的下降可引起颅内压力波。为了控制颅内高压,神经外科患者常规采用20～30度头高位。但该体位常导致颅内压(ICP)增高以及产生压力波。为探索ICP 下降与CPP 下降之间的关系,以及解释高原波发生与头位抬高的有关机制。作者基于以往研究,提出两个假 Previous studies have shown that decreased cerebral perfusion pressure (CPP) can cause intracranial pressure wave. In order to control intracranial hypertension, neurosurgical patients routinely use 20 to 30 degrees head high. However, this position often leads to increased intracranial pressure (ICP) and pressure waves. To explore the relationship between ICP decline and CPP decline, as well as to explain the occurrence of plateau wave and head elevation mechanism. Based on past research, the author proposes two falsifications
