Low phosphorus levels are associated with respiratory muscle weakness, which can result in acute respiratory problems and difficulty weaning from the ventilator. Phosphate is also contained in 2,3 DPG (diphosphoglycerate), an important component of functioning hemoglobin.

These include sepsis and acute lung injury (ALI) (20, 21, 34) caused by diverse stimuli and collectively establish a hemoly-sis paradigm for acute inflammatory disease (Fig. 1).

First, hemoglobin lacks sensitivity and specificity for iron deficiency, because levels overlap for individuals with iron sufficiency and iron deficiency (sensitivity), and there are several other causes of anemia (specificity).5,21 Second,

Blood transfusions for anemia in the hospital

A normal hemoglobin level is 11 to 18 grams per deciliter (g/dL), depending on your age and gender. But 7 to 8 g/dL is a safe level. Your doctor should use just enough blood to get to this level. Often, one unit of blood is enough. Some doctors believe that hospital patients who fall below 10 g/dL should get a blood transfusion.

This forces the user to calibrate the catheter at least daily, including entering frequent hemoglobin values.

Anemia, an abnormally low hemoglobin level and/or level of circulating RBCs, decreases the blood s oxygen-carrying capacity. Anemia can be classifi ed according to its cause, which is most often excessive bleeding, hemolysis (destruction) of RBCs, or inadequate RBC production due to either a nutritional defi ciency or a bone marrow problem.
