摘要
扰动系数是“无创脑水肿动态监护仪”的1个集成参数,是电磁波在大脑组织传递过程中相对衰减程度改变、幅值改变、速度改变、时差改变的集成,通过特定算法复合而成的具体数值,能直观反映颅内病变情况。扰动系数可早期、及时、无创地了解动脉瘤自发性蛛网膜下腔出血患者术后颅内水肿及压力变化,为动脉瘤自发性蛛网膜下腔出血患者术后颅内病情变化提供更优化的监测诊疗手段。
Perturbation coefficient is an integrated parameter of the noninvasive dynamic brain edema monitor. It is the integration of the changes in relative decay,amplitude,speed,and time difference of electromagnetic waves in the process of brain tissue transmission and can directly reflect intracranial lesions via the specific values obtained by specific algorithms.Perturbation coefficient can provide an early,timely,and noninvasive understanding of postoperative intracranial edema and pressure in patients with aneurysm spontaneous subarachnoid hemorrhage,thus providing a better monitoring,diagnosis,and treatment method for postoperative intracranial condition in patients with aneurysm spontaneous subarachnoid hemorrhage.
