Researchers have shown that low pressures within the vein (i.e., during low blood flow or stasis) can induce adhesion of white blood cells (WBCs) to the vein endothelium and then platelet activation promoting inflammation, coagulation, and catheter failure.2,3A KVO Infusion may reduce areas of stasis and risk of coagulation.

Conclusions: Low TKVO rates (10 mL/h) may not clear the PIVC tip and keep the device patent. The rate is still an approximate amount, and changes in the patient/client position can affect the flow rate. Methods: We simulated saline infusion through a 20-gauge PIVC in 2 forearm veins (3.3 and 2.2 mm) using computational fluid dynamics under various venous flow rates (velocities 3.722.1 cm/s), with a saline flush rate of 1 mL/s and TKVO infusion rates of 10, 20, and 40 mL/h.
