    • A system and a method for estimating changes in cardiac pumping capacity in response to an intervention from data recorded by an accelerometer positioned on an outer surface of the heart. Interventions such as intravenous administration of nitroprusside, betablocker, epinephrine (adrenaline), or changes in the intravascular volume such as by fluid filling, are considered. It is shown that it is possible to directly correlate changes in cardiac pumping capacity to changes in parameters or graphical representation derived from signals characteristic to the acceleration an outer surface of the heart. In particular, it is shown how the effect of the interventions can be directly read from these parameters or graphical representations, and can thereby assist in decisions regarding the treatment of a cardiac surgery patient. The invention is preferably used in a post-surgery monitoring unit for surveillance of cardiac surgery patients.
    • 一种系统和方法,用于根据位于心脏外表面上的加速度计记录的数据进行干预,来估计心脏泵送能力的变化。 考虑静脉内施用硝普钠,betablocker,肾上腺素(肾上腺素)或血管内体积变化(如通过液体灌注)等干预措施。 显示了可以直接将心脏抽吸能力的变化与参考的变化或从心脏的外表面加速度特征的信号导出的图形表示相关联。 特别地,示出了如何从这些参数或图形表示直接阅读干预的效果,从而可以帮助关于心脏手术患者的治疗的决定。 本发明优选用于手术后监测单元,用于监控心脏手术患者。
