Veterinary Emergency Fluid Rate & Infusion Calculator

Replace scrap-paper math in emergency triage. Calculate total 24-hour fluid requirements by uniting metabolic maintenance, percentage deficit restoration, and ongoing losses into exact calibrated pump rates (mL/hr) and gravity drip frequencies (gtt/min).

Algorithmic Methodology & Pharmacological Protocols

This clinical instrument executes standardized fluid therapy calculations endorsed by the American Animal Hospital Association (AAHA) and the American Association of Feline Practitioners (AAFP) Fluid Therapy Guidelines.

1. Maintenance Fluid Volume Formulation

Maintenance fluid accounts for sensible losses (urine, feces) and insensible losses (respiratory evaporation). Three standard methodologies are provisioned:

Canine Linear: 60 mL / kg / 24 hr
Feline Linear: 40-50 mL / kg / 24 hr (default 45)
Allometric Scientific: 70 * (Bodyweight_kg ^ 0.75)

The allometric equation corrects for metabolic scaling differences in smaller versus giant breed canines, preventing fluid overload in obese and pediatric subjects.

2. Deficit & Ongoing Loss Integration

Fluid deficits are resolved according to clinical dehydration assessment formulas, replenished typically over an 8 to 24-hour window:

Deficit (mL) = Weight (kg) × Dehydration % × 1000
Deficit Hourly (mL/hr) = Deficit (mL) / Replacement Window (hrs)

Gravity drip rates are derived via exact time-ratio transformations: Rate (gtt/min) = (mL/hr × Drop Factor) / 60.
