The concentration of extracellular potassium in red blood cell concentrates (RCCs) increases during storage, leading to risk of hyperkalemia. A potassium adsorption filter (PAF) can eliminate the potassium at normal blood transfusion. This study aimed to investigate the potassium adsorption capacity of a PAF during rapid blood transfusion. We tested several different potassium concentrations under a rapid transfusion condition using a pressure bag. The adsorption rates of the 70-mEq/l model were 76·8%. The PAF showed good potassium adsorption capacity, suggesting that this filter may provide a convenient method to prevent hyperkalemia during rapid blood transfusion.
红细胞浓缩液（RCCs）在储存过程中细胞外钾浓度会升高，从而导致高钾血症风险。钾吸附过滤器（PAF）可在正常输血时去除钾。本研究旨在探讨快速输血期间PAF的钾吸附能力。我们使用压力袋在快速输血条件下测试了几种不同的钾浓度。70毫当量/升模型的吸附率为76.8%。PAF显示出良好的钾吸附能力，这表明该过滤器可能为预防快速输血期间的高钾血症提供一种便捷方法。
