III.5 Shear stress/haemolysis

Abstract

Guideline III.5

A. Shear stress-related problems/haemolysis can be prevented by:

  • the use of large needles/cannulae (14/15 gauge);
  • the application of an optimal relationship between dialyzer blood flow and access diameter;
  • the prevention of highly negative arterial pressure alarms (exceeding 150 mmHg);
  • the correct positioning of cannulae and needles in the access system;
  • the correct positioning of tubings in the roller pumps;
  • minimizing recirculation;
  • the maintenance of vascular access systems in anatomically correct condition.

(Evidence level: C)
