A dry weight assessment method and system based on a kinetic model

Abstract

The invention relates to a dry weight evaluation method and system based on a dynamic model, belonging to the field of data processing. The method comprises the following steps: after acquiring regular blood test data, using a kinetic model to calculate the volume of distribution of uric acid after dialysis; calculating the volume of distribution of standardized uric acid according to the volume of distribution of uric acid after dialysis and body surface area; Volume calculates dry weight; display outputs said dry weight once estimated. Compared with the prior art, the present invention overcomes the complicated problem of measuring extracellular fluid, calculates the patient's dry body weight evaluation result only through the test data and dialysis records, and can ensure that the patient achieves the best ideal body weight after dialysis.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a dry body weight evaluation method and system based on a kinetic model. Background technique [0002] Kidney disease is a major chronic disease that seriously endangers human health and is usually treated with renal replacement therapy. Renal replacement therapy usually uses extracorporeal circulation hemodialysis to continuously and slowly remove water and solutes in the blood to replace the kidney function and minimize the impact of changes in the concentration and volume of solutes in the blood on the body. One of the purposes of hemodialysis is to remove excess water from the body. The weight before dialysis minus the dry weight is the goal of dehydration. Dry weight, also known as "target weight", is the weight of water under normal equilibrium conditions, indicating that the patient has neither water retention nor dehydration weight, which is the desired weight at the end o...

Problems solved by technology

[0004] The advantages of the bioelectrical impedance method are non-invasive, objective, fast, and low-cost. It can judge the water load state more accurately and can supplement the clinical evaluation of dry body weight. However, the disadvantages are that there are no normal values ​​and many influencing factors. Among them, electrolytes, red blood cells, protein concentration, and body temperature will all affect the conductivity, and it requires special measurement equipment, which is a bit complicated. The measurement itself takes a certain amount of time, and there is no consensus on when to measure. Periodically, all dialysis patients It is difficult to measure extracellular fluid in actual clinical application
