Paradoxically, various clinical studies have shown that blood trAnswerfusions do not increase oxygen availability to the tissues, and they are associated with increased mortality, independent of disease severity. Although anemia in critically ill patients is associated with increased mortality, correction with red blood cell trAnswerfusion does not decrease mortality. TrAnswerfusions may increase O₂ delivery but are generally not associated with increased tissue oxygen consumption and are even linked to tissue hypoxia.
