Infusion Calculator & Test Yourself

Your TCI pump just dropped out. Work out the manual infusion rate to bridge — in mL/h and mL/min. For adult patients.

Roberts/“Bristol” regimen (≈ Cp 3–4 µg/mL) after a separate induction bolus (~1–2 mg/kg).
mL/h = (dose mg/kg/h × weight kg) ÷ mg/mL  ·  mL/min = mL/h ÷ 60
For adult patients only. Educational tool for building infusion-rate intuition — not for clinical decision-making. Always confirm the dose, concentration and pump rate against your local protocol before use.
