Bicarbonate Deficit Estimate Calculator — result sheet
Estimate a bicarbonate-equivalent amount from body weight, base deficit, distribution factor, and a selected correction fraction while keeping medication decisions out of the result.

Formula and methodology
Formula: Estimated bicarbonate-equivalent amount (mmol) = body weight (kg) × distribution factor (L/kg) × base deficit (mmol/L) × selected correction fraction. The cited neonatal protocol uses 0.6 × weight × base deficit ÷ 2 for half correction.
This page makes a base-deficit estimate explicit for education and calculation review. It is not a bicarbonate prescription: the appropriate target, product, route, concentration, monitoring, and whether correction is indicated depend on a qualified clinical team.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Body weight — kg; minimum 0.1; maximum 500
- Base deficit — mmol/L; minimum 0.1; maximum 50
- Fraction of the calculated deficit — 2 choices
- Distribution factor — L/kg; minimum 0.2; maximum 1
Worked example
| Input | Value |
|---|---|
| Body weight | 70 |
| Base deficit | 10 |
| Fraction of the calculated deficit | half |
| Distribution factor | 0.6 |
Estimated amount = 70 × 0.6 × 10 × 0.5 = 210 mmol-equivalent.
Assumptions and limits
- Base deficit is entered as a positive magnitude in mmol/L.
- Body weight is current and entered in kilograms.
- The distribution factor is an explicit model input rather than a hidden constant.
- The default 0.6 L/kg and half-correction option mirror the cited institutional example, not a universal protocol.
- A full calculated amount is a mathematical scenario and is not an instruction to administer it.
- The estimate does not account for ongoing losses, ventilation, renal compensation, fluid choice, sodium load, or serial blood-gas results.
- The calculator does not convert mmol to a product volume or concentration.
- A base deficit is a laboratory-derived signal whose meaning depends on the blood-gas method and clinical context.
- Real treatment requires monitoring and current local policy, especially in infants and critically ill people.
