EMS Med Math

Paramedic + AEMT dosage, infusion & conversion calculator • v3.6
OFFLINE READY
Study/reference tool. Always verify the medication, concentration, maximum dose, route, current protocol/medical command, and your own calculation before patient care. Quick Sets are study aids based on the supplied study sheet. The AEMT view is intentionally conservative; medication authorization varies by protocol, agency, and medical director. Use the generic calculators for other orders.

Common Equations

kg: lb ÷ 2.20462
lb: kg × 2.20462
Volume to give: (desired dose ÷ dose on hand) × volume on hand
Weight dose: kg × ordered dose/kg
Gravity drip: (mL × drop factor) ÷ minutes = gtt/min
Pump rate: mL ÷ hours = mL/hr
mcg/kg/min infusion: (dose × kg × 60) ÷ concentration (mcg/mL) = mL/hr

Original Protocols

If the reader does not display on your phone, choose Open full PDF. Use the PDF reader’s search and page controls to find a protocol.

Safety & Offline Design

This calculator is intended for paramedic education and as a calculation aid. It is not a substitute for your current protocol, formulary, medication label, medical command, or independent dose verification.

The app performs arithmetic locally on the device. It does not require network access. Patient weight is stored only in local browser/app storage so it can carry between calculators; use Clear to remove it.

Medication Quick Sets were transcribed from the supplied “Medication Study Sheet 2026.” Where a vial/bag concentration was not clearly provided, the app intentionally requires you to enter the concentration actually in front of you.
