Which action will increase the K value during dialysis?

Using a proper dialyzer is essential for achieving an effective dialysis treatment, particularly in terms of enhancing the clearance of toxins, including potassium, from the blood. The dialyzer, often referred to as an artificial kidney, contains a semi-permeable membrane that allows for the passage of waste products while retaining blood cells and proteins. A dialyzer that is appropriately sized and designed for the patient’s specific needs will facilitate the optimal removal of potassium and other solutes by maximizing the surface area available for filtration and ensuring adequate diffusion across the membrane.

When the dialyzer is well-matched to the patient’s characteristics—such as blood flow rate, dialysate flow rate, and the specific solute removal needs—it will enable a higher K value during the dialysis process. This is because the proper dialyzer enhances the removal capacity for potassium ions, thus increasing their clearance from the bloodstream. This therapeutic action is critical, especially for patients with kidney failure who require hemodialysis to manage their potassium levels and avoid complications like hyperkalemia.

In contrast, factors such as incorrect target weight management, low blood flow rates, or inadequate coagulation can hinder the efficiency of dialysis and lead to suboptimal clearance of potassium. These other elements
