Continuous renal replacement therapy (crrt) in progress.Patient noted to be acutely bradycardic.Observed blood on the left side of the patient, patient found to be disconnected from crrt machine.Pressure was applied and catheters clamped, but heart rate continued to drop.Patient expired.The filter circuit on the patient return line found to be disconnected from the tego connector, which was attached to the patient's catheter.The disconnection occurred between the two products - the prismaflex set and the yellow tego connector.The tego connector attached to the vascath remained in place when the deceased was transferred for autopsy.The prismaflex circuit was sequestered and sent to the manufacturer for interrogation.The disconnection of the return line was not detectable, as the crrt default alarm parameters were not met.Suggested software enhancements for the manufacturer to explore: include incorporating rate/percentage based alarms for the return line.
