An Analysis of Hemodialysis Catheter Fluid Mechanics

Abstract Hemodialysis catheters are primarily used in instances of acute renal failure and poisonings, although there is increasing use of these catheters for long-term access, particularly in the elderly population. The typical hemodialysis catheter consists of a polymer tube with either a single or double lumen. This tube is inserted into one of three preferred catheter access sites: the femoral vein, subclavian vein, or internal jugular vein (the femoral vein is typically used for acute access only). Once in place, the catheter is available for vascular access during hemodialysis.
