Filtration characteristics of the dual-mode (Johnson and Johnson) micropore blood transfusion filter.
Stored human whole blood and red blood cells of varying age were passed through dual mode microscope blood transfusion filters. Passage through the filters resulted in markedly decreased screen filtration pressure (SFP) of the blood and increased filter weights. Numerous microaggregates were removed and SFP returned to normal. Filtration resulted in reduced platelet and white cell counts but other blood components were not adversely affected. On the basis of this research, we conclude that this micropore blood transfusion filter is effective in removing microaggregates from stored whole blood and red blood cells. It has a high capacity and rapid flow rate and is reliable during pressure transfusion.
