Blood components must be filtered during transfusion to remove clots and small clumps of platelets and white blood cells that form during collection and storage. Standard blood infusion sets contain 170 - 260 micron filters. Smaller component sets with in-line filters for plasma, platelets, and red cell aliquots are also available.
The manufacturer provides instructions for priming and use on the infusion set package. Blood sets should not be piggy-backed into other lines if this can be avoided. If they must be piggy-backed, the Injection port closest to the IV line should be used and the primary IV line shut off. Straight-type sets are primed directly with the blood component. Y-type sets can be primed with blood or Normal Saline. Usually, a new set is used for each component transfused. If 2 units are to be given consecutively and they are ABO compatible with one another, one set may be used for both as long as they are infused within 4 hours.
