Table 2 Rules for isolated abnormalities in strong ion difference (SID) and total concentration of weak acid (ATOT)
From: The meaning of acid–base abnormalities in the intensive care unit – effects of fluid administration
SID/ATOT | Isolated abnormality | Result |
|---|---|---|
SID | Increased | Metabolic alkalosis |
SID | Decreased | Metabolic acidosis |
ATOT | Increased | Metabolic acidosis |
ATOT | Decreased | Metabolic alkalosis |
