    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.
