What Bicarbonate Deficit Calculator does

How to use the Calculator Academy Bicarbonate Deficit Calculator

1. 1

   Select whether you have arterial pH plus serum bicarbonate or arterial pH plus PaCO₂ as your inputs

2. 2

   Enter the required values: arterial pH, serum bicarbonate in mEq/L, and PaCO₂ with its unit (mmHg or kPa)

3. 3

   Input patient weight in kilograms or pounds, then choose a distribution factor (0.3 standard, 0.4, or 0.5)

4. 4

   Click Calculate to view the total bicarbonate deficit, the full correction dose, and the half (partial correction) dose

Bicarbonate Deficit Calculator FAQ

Can this calculator replace clinical decision-making for bicarbonate administration?

No, the tool provides an educational estimate only. The site includes a disclaimer that results should not be used as medical advice or to guide patient treatment without physician oversight.

What do the distribution factor options mean?

The distribution factor represents the fraction of body weight treated as the bicarbonate distribution space. The default is 0.3, with options to adjust to 0.4 or 0.5 depending on clinical context.

Which input method should I use: pH plus bicarbonate or pH plus PaCO₂?

Choose the method based on your available ABG results. Both estimate standard base excess; the pH plus PaCO₂ method also derives bicarbonate values.

Are the calculated doses available in units other than mEq?

The calculator accepts weight in kilograms or pounds and outputs bicarbonate doses based on the selected distribution factor; no additional unit conversions are provided beyond the weight unit selection.
