What Is a Catheter Lumen

What is a single lumen catheter? Lumens are the inner spaces in tubes that transport liquids, gases or surgical devices during a medical procedure.

What is an IV lumen?

A multi-lumen catheter is a single catheter with more than one internal channel (called a lumen). A different intravenous infusion can be connected to each lumen, and the fluid will usually exit at a slightly different point along the catheter.

Is a single lumen a central line?

Central Venous Catheterization and Pressure Monitoring Single-lumen catheters may have single distal port or multiport tips. Triple-lumen catheters have three channels and lumens at slightly different positions on the distal cannula, providing ports for simultaneous drug infusion, blood drawing, and CVP monitoring.
