Catheter Flushing Protocol

The Infusion Nurses Society's Infusion Nursing Standards of Practice clearly define three purposes of catheter flushing; to assess catheter function, to maintain catheter patency, and to prevent contact between incompatible medications or fluids that could produce a precipitate. For effective catheter flushing, the nurse must have an understanding of technique and the equipment used within his/her institution as well as the type of catheter in use.
