About This Tool

Guideline sources: NeoHemodynamics references published paediatric and neonatal haemodynamics literature, including: European Society of Cardiology (ESC) paediatric cardiovascular guidelines, published echo nomograms (Nagueh et al. 2016 for diastolic function), and standard neonatal haemodynamics textbooks.

How results are calculated: Haemodynamic calculations (cardiac output, ejection fraction, VTI-based stroke volume, vasoactive-inotropic scores) implement published formulas. All calculations run locally in your browser; no patient data leaves this page.
