Syringe size has an impact on the risk of catheter damage. Smaller diameter syringes generate greater amounts of pressure than larger diameter syringes.1
Choose any size BD PosiFlush Saline Syringe for lower pressure due to the 10 mL syringe diameter (as compared to standard syringes). All BD PosiFlush Saline Syringes assure compliance with PICC manufacturer recommendations for flushing with a 10 mL diameter syringe.
