A large central venous catheter used to infuse fluids or to insert wires or other catheters is most appropriately referred to as a Cordis catheter.

• A. Swan-Ganz
• B. Cordis
• C. Edwards Catheter
• D. Triple-lumen indwelling catheter

Answer: (B)

A large-bore central venous catheter used for rapid fluid delivery and as a conduit to introduce wires or other devices is classically referred to by the Cordis label. Cordis catheters were originally manufactured by Cordis and became the standard term for this type of large‑bore central access that can both infuse quickly and serve as an introducer for guidewires or subsequent catheters. This differentiates it from a Swan-Ganz catheter, which is a pulmonary artery catheter used mainly for hemodynamic monitoring; an Edwards catheter, a brand that can denote various catheters but not the specific large-bore introducer function; and a triple-lumen indwelling catheter, which is a general multi-lumen line used for multiple infusions but not specifically identified as the large-bore device used to place wires or other catheters.
