Key result
Computational Fluid Dynamics simulation showed that inserting a peripherally inserted central venous catheter improves blood circulation by reducing stagnant zones and homogenizes fluids.
Why the study?
The interaction of a venous catheter with blood flow cannot be easily analyzed with common analytical methods or visualization techniques in real life.
Does the insertion of a peripherally inserted central venous catheter affect blood flow and mixture quality in a computational model?
Does the insertion of a peripherally inserted central venous catheter affect blood flow and mixture quality in a computational model?
Computational fluid dynamics modeling suggests that peripherally inserted central venous catheters may improve local blood circulation by reducing stagnant zones and that slower infusion rates optimize fluid mixing.
Demonstrates computational fluid dynamics as a hypothesis-generating tool for optimizing venous catheter design.
A catheter is a device that is inserted into the venous system to infuse treatment with controlled doses per unit of time. The study of its interaction with blood flow cannot be easily analysed with common analytical methods or different visualization techniques in real life. Computational Fluid Dynamics has become a very useful tool in a wide variety of fields of scientific study and has allowed access to the understanding of the anatomical and physiological functioning of the human body. In this work, Computational Fluid Dynamics is used to study the effects of inserting a catheter on blood flow and the quality of the mixture of blood with the various substances infused through this device. Results show that the insertion of the catheter not only does not worsen the blood circulation but improves it by reducing stagnant zones. Regarding mixture, a homogenization of the fluids in the venous area before their entrance to the heart was observed. Highest quality mixtures correspond to fewer infused fluids and at lower velocity.
