What does occlusion refer to in the context of infusion tubing?

In the context of infusion tubing, occlusion refers specifically to a blockage or obstruction that impedes the flow of fluid through the tubing. This can occur due to various factors such as kinks in the tubing, clots forming in the catheter, or air bubbles obstructing the pathway. Recognizing occlusion is critical for biomedical equipment technicians as it directly affects medication delivery and patient safety. Maintaining clear and unobstructed infusion pathways is essential for ensuring that patients receive their necessary treatments without interruption or complication. The other options pertain to different aspects of infusion processes, but do not accurately define occlusion as it relates to blockage within the tubing.
