Analysis of the treatment history data downloaded from the used prismaflex control unit has been performed.The analysis shows the alarm "malfunction code : syringe pump(5)" was triggered twice during the treatment.The alarm was triggered in connection with a new syringe installed in its holder.This type of alarm will force the control unit into a patient safe state mode; this prevents the treatment from continuing until the operator clears the alarm.The analysis of the data shows that the alarm was cleared both times it was issued.Prior to the second event, the ¿anticoag continuous rate¿ was set by the operator to zero; thereafter, the treatment continued until the operator chose to end the treatment approximately 24 hours later.A technical investigation on the prismaflex® control unit was performed by a hospital technician and he replaced the syringe pump, however it is not stated if the technician could reproduce the reported problem.The defective syringe pump has been requested and will be analyzed by the manufacturer when it has arrived.
