This alaris pump module smartsite infusion set was used on an alaris pump that was infusing pre-filter saline into the arterial chamber of the dialysis circuit (to help prevent the dialysis circuit from clotting off).Registered nurse noticed that the arterial chamber was losing its volume and air was infusing into that chamber from the most distal y-site port on the tubing.The prefilter saline was infusing at 200ml per hour, but more air than saline was infusing into that chamber.That port had never been accessed.We disconnected the tubing, primed it through with saline once again, and after it was hooked up, it infused air immediately through that same port.The air never reached the patient.The air bubbles in the dialysis circuit possibly caused the circuit to clot off, requiring a system change.There were 3 circuit changes during that sustained low efficiency dialysis run.
