I tried google but it gave me different answers. Is it because you want the medication to run faster so you hang it higher? Join NURSING.com to watch the full lesson now. Join NURSING.com to watch the full lesson now. Join NURSING.com to watch the full lesson now.
The bags are essentially connected because none of the joints are 1-way only. So they will seek a common level. That common level reaches the bottom of the higher bag before it reaches the bottom of the lower bag. Another way to put it is, at the Y joint where tubes A and B join into tube C, there is a "head" of pressure in A and B. That "head" is the density of water times the vertical distance between the joint and the top surface of the liquid. Thus the "head" will be greater in the tube connecting to the bag with the higher surface. That pressure difference between A and B will cause one of them to flow faster and even quite possibly back up into the other bag. Aside: In pharmacokinetics, there is such a thing as a "two-compartment model" that works the same way (except gravity is not the driver, but concentration). Further aside: In a high-wing airplane such as a Cessna 172, there are two fuel tanks, one in each wing, joined at a selector valve on the floor of the cabin. If the pilot makes the mistake of leaving the selector in the "both" position, and the plane is parked on a slope with one wing lower than the other, the fuel in the higher wing will drain, through the valve, and enter the slightly lower wing, causing it to fill up and overflow via its vent. IV Piggyback Medication Administration: This online course discusses guidelines and techniques in proper IV piggyback setup including back priming, bag and equipment set up, and other important steps of the piggyback infusion procedure.

Our affordable and unlimited one-year CEU plan starts at just $19.99. Upon completion of this course, the course participant will be able to:
A full IV piggyback setup with secondary tubing connected to primary tubing and secondary container positioned higher than the primary container to ensure proper and complete medication administration.
1. Lower down the secondary set to let fluid flow into it from the primary set.
2. Release the roller clamp to allow 1° solution to fill 2° tubing (don’t overfill fluid chamber). 3. Clamp off the 2° tubing once the fluid chamber is half-filled. 4. Squeeze any excessive fluid from the fluid chamber into the IV piggyback unit. Figure 1: Lowering the secondary set to let fluid flow into it from the primary set. Figure 2: Moving excess fluid into the secondary medication container. Figure 3: Attaching the new secondary medication container.
Ensure your secondary unit is at least 6” higher than the primary fluid bag.
Ensure that IV tubing is properly capped after disconnection. Do not tuck the luer adapter into the injection port.
