What does the term “VVO” stand for in intravenous terminology?

The term "VVO" in intravenous terminology stands for "Venous Valve Occlusion." This refers to a condition where the valves in the veins, which help regulate blood flow and prevent backflow, become obstructed. Understanding venous valve occlusion is crucial in the context of vascular access and infusion therapy, as it can lead to complications such as thrombosis or impaired venous return. Recognizing the significance of venous valve functionality is essential for healthcare professionals when monitoring patients who have intravenous lines or central venous catheters, as any occlusion can affect the efficacy of therapy delivery and patient safety.

Being aware of conditions like venous valve occlusion is important for timely intervention, safeguarding against potential complications that can arise from impaired venous circulation.
