Clinical Math & Conversions

- Anion Gap Compute the anion gap (Na - (Cl + HCO3)) and the albumin-corrected anion gap (+2.5 mEq/L per 1 g/dL drop below 4.0).
- Corrected Sodium for Hyperglycemia Compute glucose-corrected serum sodium using both of the published correction factors so the clinician can see them side by side.
- P/F Ratio Compute the PaO2 / FiO2 ratio - the oxygenation index from the ARDS Berlin Definition (JAMA 2012).
