It was reported that after several hours of a norepinephrine infusion being run, the bag remained full.
The rate was 63 ml/hour with a 250 ml bag, therefore the bag should have required replacement every 4 hours.
Upon investigation, the tubing inside the channel was sealed together in two areas obstructing flow.
During administration the pump was not alarming for occlusion, or empty container.
Patient required administration of additional, new drug, vasopressin, for blood pressure support and to stabilize patient's blood pressure, while the tubing was not functioning correctly.
The patient remained in icu, ultimately no effect once error was detected.
