What can occur if an IV line becomes occluded?

When an IV line becomes occluded, the primary issue is that fluid cannot flow through the line. This blockage can result from various factors, such as a kink in the tubing, a clot at the catheter tip, or even an external pressure on the line. When occlusion occurs, the intended therapy cannot be delivered to the patient, potentially leading to serious complications depending on the clinical situation, such as interruptions in medication delivery or hydration.

While fluid leakage, decreased dose accuracy, or relaxation might have relevance in different clinical contexts, they do not directly address the fundamental problem of an occluded line. The inability to deliver fluids or medications is the most critical issue that needs immediate attention in IV therapy management.
