Platelet rich red cells (PRRC) and platelet poor red cells (PPRC) are both prepared in the course of red cell production. PRRC tend to have a higher hematocrit (82 +/- 7) than PPRC (77 +/- 5), (p less than .001). There are more microaggregates present in PRRC (2.48 +/- 1.41 gm) than in PPRC (1.46 +/- 0.61 gm), (p less than .001). The infusion rate for PRRC was 4.0 X 1.8 ml/minute, and this was significantly smaller than for PPRC which was 9.7 +/- 1.7 m/minute, (p less than .001). This compares to a rate for whole blood of 32.8 ml/minute. The difference in flow rate of the two types of red blood cells is in part due to a difference in viscosity, but more inportantly due to a difference in microaggregate content. Flow rate is normalized for both types of packed cells by the addition of 100 to 150 ml of saline, while infusion time is normalized by the addition of only 50 to 100 ml of saline to the packed cell units.
富含血小板的红细胞（PRRC）和少血小板的红细胞（PPRC）都是在红细胞制备过程中得到的。PRRC的血细胞比容（82±7）往往高于PPRC（77±5），（p＜0.001）。PRRC中存在的微聚集体（2.48±1.41克）比PPRC（1.46±0.61克）更多，（p＜0.001）。PRRC的输注速率为4.0×1.8毫升/分钟，这明显低于PPRC的9.7±1.7毫升/分钟，（p＜0.001）。与之相比，全血的输注速率为32.8毫升/分钟。两种类型红细胞流速的差异部分归因于粘度的不同，但更重要的是由于微聚集体含量的差异。通过添加100至150毫升生理盐水使两种类型的浓缩红细胞的流速标准化，而通过仅向浓缩红细胞单位添加50至100毫升生理盐水使输注时间标准化。
