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
Bingo....I can't believe I didn't see this thread. BTW, looks like someone has been paying attention in their courses! Nice work.
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.
Thanks man. I just knew it coz this is finals week!
