Manufacturer Narrative

Investigation: the disposable set was returned for investigation.No defects were noted in the set.No aggregates were noted in the cassette.The access and return luers were flow tested and inspected; no issues were noted.The run data file (rdf) was analyzed for this event.There were multiple 'inlet pressure too low' pauses, and the last three chambers were collected manually because they were taking too longto be triggered by the rbc detector.A review of the lot for similar reports was carried out, none have been reported.Root cause: the rdf images show signs of some slight clumping.There were also signs of buffy coat accumulation in the reservoir which could be why the chambers were taking a long time to trigger.A platelet clump may be observed being pumped through the collect port.It is best to eliminate the clump and stop the clotting cascade as quickly as possible by adjusting the ac inlet ratio.Buffy coat accumulation can be seen through the view port, a steady defined buffy coat should not accumulate in the connector above the skimmer dam.This is most likely to occur with patients with high counts and if the pumps have paused several times.Adjusting collection preference can eliminate the buffy coat.
