🧂 Chloride Deficit
UseWhen to use: metabolic alkalosis / GI loss Cl replacement teaching math.
StrataOutputs mmol Cl to roughly close the gap — recheck labs.
LimitsWhen not to use: unstable volume / unknown TBW. · Pitfall: ignoring Na/K and acid–base. · Not a one-shot IV order.

How it works
Deficit ≈ (Cl_goal − Cl_now) × factor × weight.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Current chloride | 90 mmol/L |
|---|---|
| Goal chloride | 100 mmol/L |
| Weight | 70 kg |
| Volume factor | 0.2 L/kg |
→Estimated Cl deficit140mmol
- ΔCl：10.0 mmol/L
- Factor×wt：14.0 L

FAQ
Frequently asked questions
- Does Chloride Deficit upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is Chloride Deficit calculated in practice? Can you show a worked example?
- Inputs: Current chloride 90 mmol/L, Goal chloride 100 mmol/L, Weight 70 kg, Volume factor 0.2 L/kg → Result: Estimated Cl deficit 140 mmol（ΔCl: 10.0 mmol/L, Factor×wt: 14.0 L）
