Try to interpret «all at once» and little organized is the most common error. Then the secret to developing that skill lies in the «order», so we suggest you use only 3 steps, just 3 formulas. The diagnostic approach of acid-base disorders with the method. Traditional of Henderson-Hasselbalch does not allow to explain all disorders, but in combination with the excess of base described by Siggaard-Andersen, facilitates the diagnosis, besides that this combination is simple, rigorous and practical.
