Table 2 Formulas used to calculate serum osmolality and anion gap in DKA [12]
From: Alternative management of diabetic ketoacidosis in a Brazilian pediatric emergency department
Effective osmolality (normal = 280-290 mOsm/kg) | = | 2 × [Na+ + K+] + glucose (mg/dl)/18 |
|---|---|---|
Anion gap (normal = 12 ± 2 mEq/L) | = | Na+ (mEq/L) - [Cl- +HCO3-(mEq/L)] |
