The Terumo Capiox SX18R is a commercially available, low prime, reverse phase, hollow fiber membrane oxygenator. The oxygenator consists of a 1.8 m2 microporous polypropylene hollow fiber bundle, a 2200 cm2 tubular stainless steel heat exchanger, and an open hard shell venous reservoir with integral cardiotomy filter. The Terumo Capiox SX18R oxygenator was evaluated to determine its clinical oxygenating performance. Blood samples were drawn from 25 patients yielding 114 data points. The following parameters were recorded: blood flow, cardiac index, gas flow, gas to blood flow ratio, and oxygen fraction. Samples were assayed for hematocrit, hemoglobin, arterial and venous blood gas values, and venous oxygen saturation. The data and assay results were used to calculate arterial, venous, and membrane gas oxygen content, oxygen transfer, shunt fraction, and oxygen diffusion capacity. The Terumo Capiox SX18R oxygenator performed adequately with sufficient oxygen transfer reserve and carbon dioxide clearance under a variety of clinical conditions for the tested population.
泰尔茂Capiox SX18R是一种市售的、低预充量、反相、中空纤维膜式氧合器。该氧合器由一个1.8平方米的微孔聚丙烯中空纤维束、一个2200平方厘米的管状不锈钢热交换器以及一个带有一体式心内吸引过滤器的开放式硬壳静脉贮血器组成。对泰尔茂Capiox SX18R氧合器进行评估以确定其临床氧合性能。从25名患者身上采集血样，得到114个数据点。记录了以下参数：血流量、心脏指数、气体流量、气/血流量比和氧分数。对样本进行血细胞比容、血红蛋白、动脉和静脉血气值以及静脉氧饱和度的检测。数据和检测结果用于计算动脉、静脉和膜气体氧含量、氧转运、分流分数和氧扩散能力。在各种临床条件下，对于受试人群，泰尔茂Capiox SX18R氧合器表现良好，具有足够的氧转运储备和二氧化碳清除能力。
