What this is
Convert a vasopressor dose order into a pump rate, or a pump rate back into a delivered dose. Sophie Well handles the common ICU agents - norepinephrine, epinephrine, phenylephrine, dopamine, vasopressin, dobutamine - with their conventional dose units (mcg/kg/min for the catecholamines, mcg/min or units/min for the fixed-dose pressors). Enter the agent, the bag concentration, and either the desired dose or the running rate, and the tool returns the missing side of the equation along with the dose-per-minute and the dose-per-kg-per-minute.
When to use it
Use this when admitting a transferred ICU patient whose previous pump was running at a rate without a documented dose, when titrating a pressor to a MAP goal and you want to see what each rate change actually delivers, or when a bag concentration changes mid-shift and you need to keep the dose constant across the swap. The math is deterministic; the clinical decision (which agent, which dose, when to add or escalate) lives with the bedside team and the active institutional protocol.

Standard infusion math: rate (mL/hr) = (dose per min / concentration per mL) * 60.

Worked example: Dopamine at 0.1 mcg/kg/min, 70 kg, 64 mcg/mL: ~6.56 mL/hr (forward); 6.56 mL/hr -> ~0.1 mcg/kg/min (reverse).
