Hydrodynamic Evaluations of Four Mock Femoral Venous Cannulas
Objective: To report the results of four mock femoral venous cannulas and the
hydrodynamical superiority of one of them, which is the completely punched
(CP) model, upon the other three.Methods: Four simulated femoral venous cannulas (single-stage, two-stage, multi-stage,
and CP model) were designed from a 1/4 ” x 1/16” x 68 cm polyvinyl chloride
(PVC) tubing line for testing. Holes on the PVC tubes were opened by a 5 mm
aortic punch. In order to evaluate the cannulas' drainage performance,
gelofusine was used as fluid. The flu .. .
