Abstract: A system and method for determining the amount of fluid to be removed from a dialysis patient is disclosed. The system utilizes sensors and a computer. The computer obtains the input parameters from the sensors, along with information added directly by the user, and performs a forward algorithm to determine a recommended change in patient fluid level. As fluid is removed, the effect of the removal on the parameters is detected by the sensors and re-transmitted back to the computer. The computer then performs a backward algorithm to refine the variables used in the forward algorithm and obtain more accurate results. The system and method provide for changing the amount of fluid removed from the patient based on the results of the algorithm and the data received from the sensors.

Abstract translation: 公开了一种用于确定要从透析患者移除的流体的量的系统和方法。 该系统利用传感器和计算机。 计算机从传感器获取输入参数以及用户直接添加的信息，并执行前向算法来确定患者液位水平的推荐变化。 当流体被去除时，通过传感器检测对参数的去除效果，并将其重新传送回计算机。 然后，计算机执行反向算法来细化在前向算法中使用的变量并获得更准确的结果。 该系统和方法提供了基于算法的结果和从传感器接收的数据来改变从患者移除的流体的量。

Abstract: Systems and methods are provided for determining an estimated risk of arrhythmia during or after dialysis based on changes in serum potassium concentration of a patient and an amount of fluid removed from the patient during dialysis. The systems and methods allow for a determination of a risk that arrhythmia will occur due to the changes in potassium and fluid volume of a patient during dialysis, and for optimizing a dialysis prescription in order to minimize the risk of arrhythmia.
