The rapid infuser has not been returned to belmont for investigation, nor was information about the disposable set provided; therefore, we are unable to confirm the report that the device would not infuse blood higher than 90 ml/min.The system will reduce the infusion rate in order to keep the pressure in the line under the pressure limit, which may cause the flow rate to slow down or prevent it from reaching the set rate.In the event that the flow rate is slowing down or will not go at the set rate, the operator's manual provides the following recommended operator actions: 1) "check and remove kinks or obstructions in the tubing"; 2) "use the appropriate infusion set recommended in the guide, match the infusion set to flow rate and fluid type"; and 3) "increase flow by increasing the pressure limit.Change the pressure limit in calibration/setup to a higher limit (maximum pressure limit is 300 mmhg)".As high pressure may occur if the infusion site is not well placed or the catheter bore size is too small, the operator's manual instructs the user: "select an appropriate cannula size for the decided flow rate" and provides a chart to help the user choose an appropriate cannula size for the desired flow rate and infusate.The manual also cautions that "a single dedicated intravenous access should be used exclusively for infusing blood components and solutions compatible with blood." the manufacturing records for this serial number were reviewed and no anomalies were found during the manufacturing process.Without further information, it is difficult to determine what occurred.Belmont will continue to follow up with the user facility to obtain additional details about the case.Should additional information become available, a supplemental report will be provided.
