Veterinary CRI Infusion Rate Calculator

Calculate veterinary constant rate infusion pump rates and bag-addition amounts from unit-normalized CRI dosing inputs.

Cited standard/category: Health & Clinical. Standard CRI formula: pump rate = (dose x weight) / concentration, with all dose and concentration units normalized.

Infusion Inputs

Direct pump rate uses stock drug concentration.
kg
mg/mL

Fluid Bag Method

Optional compounding worksheet for CRI delivered through fluids.
mL
mL/hr

Shows a warning when calculated stock drug volume exceeds 10% of the entered fluid bag volume.

This calculator is a math worksheet for veterinary CRI dosing documentation. Confirm the prescribed drug, concentration, route, compatibility, dilution, patient monitoring plan, and current clinical protocols before use.

About the Veterinary CRI Infusion Rate Calculator

Veterinarians, technicians, and emergency teams use a veterinary CRI infusion calculator to convert weight-based drug doses into milliliters per hour or bag-addition plans. It supports constant-rate infusion setup by tying together patient weight, prescribed dose, drug concentration, fluid volume, and pump rate, reducing manual math during anesthesia, analgesia, and critical care.

How it works

  1. Enter patient weight and confirm the unit used by the prescription.
  2. Add the ordered dose rate and drug concentration.
  3. Choose direct syringe delivery or the bag method.
  4. Review milliliters per hour, total drug amount, and infusion concentration.
  5. Document the calculation and have the clinical order independently checked.

Frequently asked questions

What units are commonly used for veterinary CRI orders?

Orders may use units such as milligrams per kilogram per hour, micrograms per kilogram per minute, or units per kilogram per hour. Convert units carefully before setting the pump.

How does the bag method differ from a syringe pump CRI?

The bag method adds a calculated drug amount to a fluid bag and delivers it at a set fluid rate. A syringe pump delivers a prepared concentration directly at a calculated milliliter-per-hour rate.

Why is patient weight so important for CRI dosing?

Most veterinary CRIs are weight based, so an incorrect weight changes the delivered dose. Recheck weight units, especially when converting between pounds and kilograms.

Can the calculator choose a safe drug dose?

No. It performs arithmetic from the dose ordered by a veterinarian. Drug selection, dose range, compatibility, monitoring, and patient-specific risk require clinical judgment.
