Overview :

Davis et al used the admission base deficit for a trauma patient to predict the blood transfusion needs. This can help identify a patient who may require significant blood product support. The authors are from the Fresno Campus of the University of California San Francisco.

If base excess is reported, then a base deficit is a negative number.

If base deficit is reported, then a base deficit is a positive number.

Base Excess	Interpretation
>= 3 mmol/L	base excess
-2 to 2	normal
-3 to -5	mild base deficit
-6 to -9	moderate base deficit
<= -10	severe base deficit

Base Excess	Units Packed RBCs first 24 hours	Total Units Packed RBCs	Total Units FFP
>= -2	0-1	1-2	0-1
-3 to -5	1-2	2-3	0-1
-6 to -9	3-4	5-6	1-2
<= -10	8-9	9-10	3-4
