Nicutools

Twenty-five evidence-based clinical calculators for neonatal intensive care, designed for the bedside. Built by an Australian neonatal clinician for fellow NICU professionals.

CALCULATORS INCLUDED

Respiratory & Physiology • Alveolar-arterial O₂ gradient • Altitude physiology • Base excess • Low-flow O₂ delivery • Mean airway pressure • Nitric oxide delivery • Oxygenation index (with ECMO threshold alert)

Fluids & Nutrition • Dextrose infusion preparation • Glucose infusion rate (GIR) • Fluid & feeds rate

Survival & Outcomes • Extreme preterm outcomes • Diaphragmatic hernia survival probability • ECMO risk in diaphragmatic hernia

Resuscitation & Procedures • Apgar clock & CPR metronome • ET tubes & umbilical catheters • Partial exchange transfusion (polycythaemia) • Percutaneous long lines

Gestation Calculators • Corrected gestational age • Gestational age at birth

Converters & Measurements • Weight converter • Bilirubin units (μmol/L ↔ mg/dL) • Glucose units (mmol/L ↔ mg/dL) • Pressure units (kPa ↔ mmHg) • Body surface area • Percentage weight loss

DESIGNED FOR THE BEDSIDE

• Works offline — no data leaves your device, ever • iPad-adaptive layout shows sidebar + calculator side by side • System-wide search via Spotlight • Haptic feedback on clinical warnings • Dark mode and pressure-unit preferences sync across all calculators • In-app Algorithm and References dialogs explain the maths and cite primary sources where applicable

CLINICAL DECISION SUPPORT ONLY

Nicutools is a reference tool for qualified healthcare professionals. All calculations must be independently verified against your local protocols and your patient's circumstances. Not a substitute for clinical judgement.

The free web version is at nicutools.org. This iOS app adds native iOS conveniences — Spotlight search, iPad split-view, haptics, true offline support, and no analytics.
