What is a secondary IV administration set also known as?

The secondary IV administration set is commonly referred to as a piggyback set. This terminology arises from the method in which the secondary set is attached to the primary IV line, effectively "piggybacking" onto it. When using a piggyback set, a secondary bag of fluid or medication is infused intermittently alongside the primary infusion, allowing for the delivery of medication without interrupting the primary fluid flow.

The piggyback set typically has a higher position in relation to the primary bag, enabling gravity to assist with flow and ensuring that the secondary infusion occurs when required. This method is particularly useful for administering medications that are needed sporadically—not continuously—allowing for efficient and effective management of patient care. In contrast, the other options refer to different IV administration setups or devices that do not specifically describe the secondary administration method.
