  • Contact CareFusion to discuss how to check the springs housed in the plunger holder.

  • If a broken spring is identified, contact CareFusion to arrange for the faulty springs to be replaced.

  • Ensure all syringe pumps are regularly maintained and serviced in accordance with the manufacturer’s recommendations.

This issue may affect all syringes (recommended and non-recommended) when used in the specified Alaris syringe pumps.
