Designed to eliminate syringe-induced reflux*

	What is syringe-induced blood reflux?	*Average reflux as measured in 4Fr PICC; data on file at BD.
	Syringe-induced blood reflux occurs during a flush procedure when the rubber stopper meets the end of the syringe. Since it is rubber, it will compress and rebound when pressure is released; creating a vacuum that draws blood back into the catheter.1 View reflux demonstration
	How do I overcome syringe-induced blood reflux?
	To overcome syringe-induced blood reflux use a prefilled syringe for catheter flushing that is designed to overcome this problem.1 Positive displacement valves address disconnect reflux, not syringe-induced reflux.2

BD PosiFlush™ Saline Syringes are designed to eliminate
syringe-induced blood reflux.*

BD PosiFlush Saline Syringes are designed to eliminate syringe-induced blood reflux*,
enhancing catheter maintenance protocols.

Graphic depicts the average amount of blood aspirated into the catheter
upon completion of flush procedure if positive pressure technique is not correctly applied.
