Dr. Paul Hebert and his colleagues from the University of Ottawa say in the New England Journal of Medicine: "Our findings indicate that the use of a threshold...as low as 7 grams of hemoglobin per deciliter...was at least as effective as and possibly superior to a liberal transfusion strategy...in critically ill patients."
It is well-known that giving too much blood or other infusions can cause heart attacks or water on the lungs because of the effort required to pump the extra liquid around the body. But the researchers found these factors could not explain the differences they found.
Ahhhh.... so it is improper administration of blood that causes problems, not the blood itself.
Since you are using this article to state your position, does this mean that you will accept properly administered blood?
