Nefarias Bredd

Hey, came across this last night and trying to figure out why it happened. So I had 2 infusions to hang, by gravity. Set up the primary, had it hanging low off the stretcher pole. Set up the piggyback, and it’s way high from the ceiling hook. But then when I hooked everything up to the patient both were dripping at the same time. The only thing that I could think of in the moment is that using two primary tubings instead of the short piggyback might have affected something, but then again I’m pretty sure I’ve done it this way and it worked fine before ?
