**Back-flush/Back-Prime Secondary Line**

[twinjeep97]

Hello,

*With use of Baxter Pump*

In this situation, there will be 2 bags, with the NS hanging below ATB. Another client is due for another 50mL dose of an ATB, so we must switch out the ALMOST empty secondary bag. When I go into room I will hit "stop." The connection from the secondary (portless) to main line is done by use of a "alligator clip." Once I hit stop, I will leave both lines unclamped and LOWER the 2ndary bag below the mainline bag. The lower the secondary bag, the faster the fluid will flow from mainline back up through secondary line into the drip chamber (hence bubbling). Once the drip chamber is almost full I will then squirt the collected fluid from the chamber into the old bag (clearly the line). I will then take spike out of old bag and spike new ATB bag UPSIDE DOWN while keeping clamp open on 2ndary line, then fill drip chamber to 1/3-1/2 full. Then would I program 2nd rate, 2nd volume, 2nd start, While ensuring drops are visible in the drip chamber prior to leaving room. At this time, the primary IV line should NOT be dripping (but will take over once the VTBI on 2nd pump is finished infusing). IS this correct? I really appreciate anyones input, suggestions, criticism.

Thanks,
