All Renal/Electrolytes Nav Equations
- Sodium Correction Rate in Hyponatremia
Calculates recommended fluid type, rate and volume to correct a patient's hyponatremia slowly (or more rapidly if seizing). - Winters’ Formula for Metabolic Acidosis Compensation
Calculates the expected pCO2 in a purely metabolic acidosis. - Free Water Deficit in Hypernatremia
Estimates the free water deficit in hypernatremia using a patient's estimated total body water. - Transtubular Potassium Gradient (TTKG)
Determines if potassium derangements are due to renal or extra-renal cause. - Stool Osmolar/Osmotic Gap
Determines if chronic diarrhea is osmotic or secretory in nature. - Sodium Deficit in Hyponatremia
Calculates sodium quantity missing in hyponatremia. - Serum Osmolality/Osmolarity
Calculates expected serum osmolarity, for comparison to measured osmolarity to detect unmeasured compounds in the serum. - MDRD GFR Equation
Estimates glomerular filtration rate based on creatinine and patient characteristics. - Fractional Excretion of Urea (FEUrea)
Determines the cause of renal failure similar to the FENa, but can be used in patients on diuretics. - Fractional Excretion of Sodium (FENa)
Determines if renal failure is due to pre-renal, post-renal, or intrinsic renal pathology. - Sodium Correction for Hyperglycemia
Calculates the actual sodium level in patients with hyperglycemia. - Creatinine Clearance (Cockcroft-Gault Equation)
Calculates creatinine clearance according to the Cockgroft-Gault equation. - Calcium Correction for Hypoalbuminemia
Calculates a corrected calcium level for patients with hypoalbuminemia. - Bicarbonate Deficit
Calculates the amount of bicarbonate deficit. - Anion Gap
Calculates the anion gap to check for metabolic acidosis.
