You have 250 mg aminophylline in 250 mL D5W. Conversely, other research has demonstrated the impact of excessive forces of the vessel endothelium.5 This suggests that intermediate shear forces (24 dynes/cm2) represent a sweet spot for injection (bolus) and infusion.

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.
