Strong ion gap (Stewarttechnique) is far superior to traditional method in explanation of acid base disorders. It is also useful in certain unique conditions where traditional method may show a falsely normal number. Having this in your calculator will ensure thT more practitioners use this great technique

Stewart's method of acid base
(Base Deficit) + (Strong Ion Difference-38) + 2.5(4.2-Albumin) - Lactate

Strong ion différence
= [HCO3-]+[Albumine x (0,123 x pH - 0,631) + phosphore x (0,309 x pH - 0,469) = 40 +/- 2 meq/L
Very usefull for acidobasic troubles in intensive care.
