Investigation: the run data file (rdf) was analyzed for this event.The analysis of the run data file did not identify a conclusive root cause for the presence of air in the donor line for this procedure.No unusual process variable was identified and the signals in the run data file indicate that the trima accel system operated as intended.Specifically, the pressure signals and the pumped volume values were all within the expected range during tubing set test, ac prime, and blood prime states of the procedure.Based on the image taken and the known diameter of the tubing, we can conservatively calculate the amount present past the final point of detection to be 0.052 ml.Based on a patient bodyweight of 189 lbs (86 kg), we can calculate the worst case ml/kg air transfusion dose to be 0.00060 ml/kg in this situation.One used trima set containing blood was returned for investigation.It was noted that blood had circulated throughout the set and the platelet bags were removed.The disposable set was visually evaluated for any mis-assembly, leak location, or defect that could have contributed to the reported incident.Possible leak around inlet trap filter.All pressure sensors were inspected and determined to be functioning properly.Gravity was used to manipulate fluid throughout the set and no fluid flow or line obstruction issues were noted.All clamps were checked and were functional.No bond gaps were observed.A disposable complaint history search was performed for this lot and found one report for similar issues on this lot.The customer history report indicates there were five reports of similar issues.Investigation is in process, a follow up report will be provided.

Event Description
|
The customer reported that during an apheresis platelet procedure on a trima device two air bubbles were observed in the donor line past the manifold during the first return.The staff immediately clamped the line, but one bubble went into the needle and possibly the donor.The other bubble was in the donor line.The patient was monitored for 30 minutes in the canteen and had no symptoms.All leur connections were tight and there was no clotting in the channel or in the return reservoir.They said the blood diversion pouch was not inflated with air, there were no alarms, the donor was connected prior to ac prime, and there was no air being drawn in through the ac line or filter.No medical intervention was reported.Full donor unit id#: (b)(6).
