Homogeneous microaggregate-free whole blood at +5 degrees C was transfused at constant pressures of 20 and 40 kPa through two micro-filtration and blood warming devices, and the temperature of the blood was recorded before it reached the venous cannula. The flow rates with the Fenwal system were 58 and 139 g/min, whereas the micro-filter MF10B combined with the Portex Coil allowed flow rates of 143 and 224 g/min. The warming capacities of the two warmers were almost equal and this did not prove to be their weak point. The infusion temperature varied considerably during the transfusion. Increasing the priming volume of the coil would raise the mean infusion temperature. A pressure infusor (Fenwal) was tested, and the internal pressures of the blood bag and the infusor were determined separately. The bag pressure differed significantly from the infusor pressure as the blood bag emptied, making the usefulness of the infusor manometer questionable.
在5摄氏度下的无均质微聚集体全血，通过两个微滤和血液加温装置，以20千帕和40千帕的恒定压力进行输注，并在血液到达静脉插管之前记录其温度。Fenwal系统的流速分别为58克/分钟和139克/分钟，而与Portex盘管相结合的微滤器MF10B的流速为143克/分钟和224克/分钟。两种加温器的加温能力几乎相同，这并未证明是它们的弱点。在输注过程中，输注温度变化很大。增加盘管的预充量会提高平均输注温度。测试了一种压力输注器（Fenwal），并分别测定了血袋和输注器的内部压力。随着血袋排空，血袋压力与输注器压力有显著差异，使得输注器压力计的实用性受到质疑。
