What type of IV set would be appropriate for an order of 250 mL of NS for KVO?

In the context of administering 250 mL of Normal Saline (NS) for keep vein open (KVO) purposes, microdrip tubing is particularly suitable. This type of IV set delivers a smaller volume of fluid per drop, which allows for more precise control over the rate of infusion.

When the goal is to maintain venous access (as in KVO), it’s important to use an IV set that can facilitate a very slow and steady flow, which microdrip tubing achieves effectively since it allows the healthcare provider to administer smaller amounts of fluid more accurately. This is essential when dealing with KVO, where the infusion rate must be kept minimal, often around 10-25 mL per hour, in order to maintain patency of the IV line without overloading the patient.

Using macrodrip tubing would typically result in larger drops and a faster infusion rate, making it less suitable for KVO where precision is necessary to prevent fluid overload. Thus, microdrip tubing is the optimal choice for this scenario, ensuring that the fluid is administered safely and effectively.
