What does Base Excess tell you on an ABG? How do you interpret it?

What does Base Excess tell you on an ABG? How do you interpret it?

As an RT student I'll try to give you an answer. Normal base excess in a blood gas is +-2mEq/L. If there is a positive BE (greater than +2) then this indicates that there has been a gain of a base or loss of acid due to non respiratory causes.
However if there has been a negative base excess (less than -2) then there has been a loss of base or a gain of acid from non respiratory causes.

Hope this helps

Also be aware that some people refer to -BE as base deficit. Can be confusing if you've never heard of it that way before.
