Infusion/drop calculator
Infusion rate in ml/h and drops/min from volume and time – or duration from rate
Scientific basis
Control
Dose calculations for children are error-prone (decimal point errors, units, confusion of mg and ml). The calculated amount must be checked against the prescribing information or hospital standard and the maximum dose; the calculation line makes cross-checking easier.
Calculation aid for healthcare professionals: the calculator reproduces what the sources cited assign to the inputs. Clinical assessment and every treatment decision remain with the treating physician. Inputs and results are not stored.
