Dehydration Fluid Deficit Calculator
Result
Dehydration Fluid Deficit Calculator Calculate fluid deficit in dehydration. Deficit = (Current Na - Normal Na) × TBW / Normal Na — free online calculator.
Formula
- Dehydration Fluid Deficit Calculator calculates its result from Na Normal, Tbw, Na Current. It uses the formula Deficit = (Na_current - Na_normal) × TBW / Na_normal. Change any input to recalculate the result instantly. This is an informational calculation and is not medical advice.
- The main inputs are Na Normal, Tbw, Na Current. Enter them in the units and format shown in the calculator.
- Use the measurement units shown beside each field. The result is an estimate and should be interpreted in context.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Dehydration Fluid Deficit
- Na Normal: 2
- Tbw: 3
- Na Current: 4
Using Na Normal = 2, Tbw = 3, Na Current = 4, the calculated result is 3.
