Potassium supplementation calculator

Estimate potassium supplementation concentration math for small-animal fluid planning. This tool shows mEq to add and the delivered mEq/hr at the entered fluid rate. It is arithmetic support only; verify the final plan against current protocol and reference.

Input

Enter the supplementation math

Use the intended fluid rate and desired potassium concentration in the bag. Add bag size when you want the per-bag amount shown directly.

Weight unit Body weight

Current fluid rate Desired potassium concentration

Bag size optional Concentration unit

Fluid-rate unit Bag-size unit

Result

Potassium result

Enter the fluid rate and desired concentration to calculate delivery math and the amount to add.

Awaiting calculation

Confirm body weight and unit.
Enter the intended fluid rate in mL/hr.
Add bag size when you want the bag amount shown directly.

Formula

Formula audit trail

1. Convert body weight to kg when weight is entered in lb.

2. Delivered mEq/hr = fluid rate (mL/hr) x desired concentration (mEq/L) / 1000.

3. Delivery by body weight = delivered mEq/hr / body weight in kg.

4. Potassium to add to a bag = bag volume (L) x desired concentration (mEq/L).

Rounding is for display only. This release shows arithmetic only and does not choose whether supplementation is indicated.

Calculation steps will appear here for verification.

Safety checks

Review before use

Arithmetic support only.
This tool does not recommend whether potassium supplementation is indicated.
Verify the final plan against current protocol, reference, and patient monitoring.

Quick reference

Potassium supplementation in dogs and cats (quick reference)

Potassium is supplemented when hypokalemia or ongoing losses make replacement part of the fluid plan.
In IV fluids, mEq/L means the amount of potassium present in each liter of the final bag.
Concentration matters because it sets how concentrated the fluid is; delivery rate matters because mEq/hr changes with the fluid rate.
Protocol choices depend on species, severity, route, renal status, monitoring, and the broader clinical context.
Use the potassium calculator above for exact math.

Basis

Basis and limits

Calculation basis: delivered mEq/hr = fluid rate x desired concentration / 1000. Per-bag amount is shown only when bag size is entered.

This tool provides arithmetic estimates based on commonly used veterinary formulas and reference values. It does not select treatments or replace clinical judgment. Always verify values against current protocols and product labels before use.

Reference ranges and approaches align with standard veterinary resources (e.g., emergency and internal medicine references such as Merck Veterinary Manual and common clinical guidelines).
