Flow rates and pressure recording accuracy were compared for Argyle 14-, 16-, and 18-ga double-lumen and Edwards 7-Fr triple-lumen CVP catheters. Physiologic saline solution was pressure-infused into dogs through one lumen and CVP was measured via the other lumen. CVP accuracy was unaltered by simultaneous rapid infusion in either the double-lumen or triple-lumen catheters. In a separate in vitro experiment, physiologic saline and blood were pressurized at 100 to 400 mm Hg and infused through each port, and volume delivery per minute was measured. Only the 14-ga double-lumen catheter was adequate for the administration of a large amount of crystalloid solution. However, it was not large enough to permit the rapid infusion of blood. On the other hand, large volumes of both crystalloid and whole blood could be delivered through the 7-Fr triple-lumen catheter.
比较了阿盖尔14号、16号和18号双腔中心静脉导管以及爱德华兹7F三腔中心静脉导管的流速和压力记录准确性。通过一个管腔向狗体内压力输注生理盐水，并通过另一个管腔测量中心静脉压。双腔或三腔导管同时快速输注时，中心静脉压的准确性不受影响。在另一个体外实验中，将生理盐水和血液在100至400毫米汞柱的压力下通过每个端口输注，并测量每分钟的输液量。只有14号双腔导管足以输注大量晶体溶液。然而，它的尺寸不足以允许快速输注血液。另一方面，大量的晶体溶液和全血都可以通过7F三腔导管输注。
