About ICU IV Free
ICU IV Free is a safety-focused clinical tool designed to support continuous intravenous infusion calculations in intensive care and critical care settings, especially in limited-resource environments. It includes the complete infusion-calculation engine, free, with no registration and no saved patient records.
The calculator is:
Bag-based (100–500 mL)
Continuous-infusion only
Suitable for pump and gravity use
Optimized for ICU nurses, technicians, and physicians
This tool supports calculations only. It does not provide protocols or clinical decisions.
Free vs. Professional
Free deliberately excludes patient-information and saved-record fields because it is an anonymous, single-calculation tool. Professional adds patient-linked records, monitoring, IV labels and institutional printing for documented hospital workflow. It uses the same calculation engine and includes a paid-product trial.
ICU IV Free is free to use. If it has helped you and you would like to support its independent maintenance, clinical review and continued development, contact official ENKI Support on WhatsApp. Support is entirely voluntary, unlocks no features and does not purchase clinical services.
Dose ranges reflect current evidence for adult ICU patients. Neonatal, paediatric, and renal/hepatic dose adjustments are not within scope of this calculator. See References for full source list.
Disclaimer
ICU IV Free supports infusion preparation and rate calculation. It does not replace medication orders, pharmacy verification, institutional protocols, compatibility references, independent double-checks, infusion-pump safeguards or clinician judgment.
