Dry body weight evaluating method based on dynamic model, and system

Abstract

The invention relates to a dry body weight evaluating method based on a dynamic model, and a system, wherein the method and the system belong to the data processing field. The method comprises the following steps of after obtaining regular blood testing data, performing calculation by means of the dynamic model, and obtaining an after-dialysis uric acid distribution volume; calculating a standarduric acid distribution volume according to the after-dialysis uric acid distribution volume and a body surface area; calculating the dry body weight according to the standard uric acid distribution volume; and displaying and outputting the dry body weight which is evaluated once. Compared with the prior art, the method and the system have advantages of overcoming a complicated problem in measuringextracellular fluid, calculating a dry body weight evaluating result of the patient just through testing data and dialysis records, and ensuring an optimal ideal body weight of the patient 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
