Pulling back too hard on PIV and getting air.

[roddycn, BSN]

What is it called when you pull back too hard on a PIV and get air??? I am racking my brain and I can't remember the specific term it's called!!! Basically the PIV can suck down on the vasculature and then you get air back in your syringe.

Why are you pulling back?

Turbulence, thrill?

You dont get air unless the iv has come out of the patient's arm. You get a vacuum.

Either way its bad from. A peripheral iv that's not giving blood return with a gentle pull will never start giving blood when you pull harder. You just damage the vein. Manipulate its position, flush, apply a tourniquet, have the patient make a fist, etc, instead. But dont pull harder.

What's it called? No idea. Just dont do it.

Can somebody explain this?

IF an IV is positional, or against a valve, withdrawing can help. But what is pulling harder? How hard do you have to pull?

And, where is the air coming from.

I draw a lot of blood from a lot of PIVs, but don't understand the question.
