(b)(4).Although the device involved in the reported incident was not returned for evaluation, the device history logs were provided by the user facility for evaluation.Based on the log review it was determined that during the course of the infusion the pump alarmed multiple times for pressure alarms.These alarms are caused by blocked iv lines or by a blocked iv access, and until the iv is cleared the pump is not able to deliver medication to the patient.As a result the time it would take to infuse the full dose would be impacted.No adverse quality trends of this nature were identified during the complaint review process for the reported catalog number.Based on the results of the investigation, the pump operated as intended.If additional information becomes available, a follow up report will be submitted.
