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.
