Figure 2. Influence of Washing Red Blood Cells on Total Unit Cell Free Hemoglobin and Percent Hemolysis.

Figure 2

Red blood cells of late duration storage were exposed to either the Cell Saver Elite or Cobe 2991 washing device. Neither the total free hemoglobin in the unit (A) nor the % hemolysis (B) were different in pre-wash conditions. Washing by the Cell Saver Elite, but not the Cobe 2991, produced significant elevations in total free hemoglobin and % hemolysis. Furthermore, post-wash effects were significantly different between devices. * P <0.05 vs within wash device; † P <0.05 vs Cell Saver Elite.
