ABSTRACT

The physicians exhibit empirical agreement in their decisions to transfuse. The therapeutic goal of a blood transfusion is to increase oxygen delivery according to the physiologic need of the recipient. The assumed benefit of an increase in the red cell mass does not always translate into a true benefit in terms of oxygen transport in critically ill patients. In the absence of a physiologic need in a stable, non bleeding patient, an attempt to achieve a rise in hemoglobin level, alone, is not a good reason to give a transfusion. The basis for marking transfusion decisions remains unclear. As outlined earlier, significant benefit occurs when physiologic need exists, and, if significant benefit is anticipated, transfusion can not be necessary.
