Build the infusion. Verify the rate.
A clinician-designed ICU infusion engine that turns the available drug supply, diluent, patient weight and target dose into a transparent preparation and pump rate.
Free ICU IV infusion calculator — concentration, mL/hour, gravity rate and bag duration without an account or patient record.
LOCAL CALCULATION · NO PATIENT IDENTIFIERS · OFFLINE-CAPABLE
Illustrative calculation — not a live patient result.
Everything the calculation engine can do
ICU IV Free is an IV infusion rate calculator and drug dilution calculator built for continuous IV medication in the ICU. It includes the complete infusion-calculation engine — the same calculations used in the Professional edition, with no functionality withheld.
Drug concentration
Final concentration from ampoule strength, count and bag/syringe volume.
Pump rate & mL/hour calculation
Weight-based infusion calculation of pump rate in mL/hr and mL/min from target dose and body weight.
Gravity infusion rate
Macrodrip and microdrip drop rates, suppressed automatically for high-risk drugs.
Bag-duration estimate
Estimated time to bag completion at the calculated rate.
Preparation instructions
Step-by-step preparation text specific to the selected drug and diluent.
Safety warnings
Forbidden-diluent checks, high-concentration alerts and high-risk drug handling.
Supported medication categories
28 medication entries across 7 clinical categories. See references for the guidelines behind each dose range.
Vasopressor infusion calculations cover norepinephrine infusion, epinephrine infusion and vasopressin infusion. Sedation infusion calculations cover propofol infusion, midazolam and dexmedetomidine. Anticoagulation covers heparin infusion, and metabolic/endocrine covers insulin infusion.
Three steps, no account
Select the drug and preparation
Choose the medication, ampoule strength, diluent and bag or syringe volume.
Enter body weight and target dose
Only the variables the calculation needs — nothing else is requested.
Get the pump rate and summary
View concentration, pump rate, gravity rate and an anonymous calculation summary.
Privacy architecture
ICU IV Free is built so that patient-identifying information is never collected in the first place.
No patient name, MRN, bed, hospital or physician fields
Body weight is used only for the current calculation, in memory
No persistent clinical records or saved infusion sessions
No multi-patient ICU Monitor in the Free edition
Closing or refreshing the page discards the current calculation
No clinical values included in analytics or transmitted externally
Free versus Professional
ICU IV Free deliberately has no patient-information fields: it is an anonymous, single-calculation tool and creates no patient record. ICU IV Professional adds patient-linked records, active-infusion monitoring, alerts, IV labels and institutional printing for documented hospital workflow. Patient details in Professional exist for clinical identification and reporting—not to change the calculation engine. The paid Professional application includes a trial.
