THE DEVELOPMENT of plastic containers with connected satellite bags for the collection of whole blood ushered in a new era of blood component therapy. Even before that time, it was recognized that a deficiency in red blood cell (RBC) oxygen-carrying capacity was best treated by the transfusion of packed red blood cells (PRBC).
