Fick Cardiac Output Calculator (US Units)
Patient Data
Blood Gas Values
Note: This calculator uses the Fick principle to estimate cardiac output based on oxygen consumption and the arteriovenous oxygen content difference.
Formula: CO = VO₂ / (CaO₂ - CvO₂) × 10
where CaO₂ = (Hgb × 1.36 × SaO₂) + (0.0031 × PaO₂)
and CvO₂ = (Hgb × 1.36 × SvO₂) + (0.0031 × PvO₂)
