Cardiac Output Calculator

Calculate cardiac output using the Fick equation and stroke volume method. Also estimates cardiac index and systemic vascular resistance.

Cardiac Output (Fick)

5 L/min

Cardiac Output (HR x SV)5.04 L/min

Cardiac Index2.78 L/min/m²

SVR (estimated)1,408 dynes·s/cm⁵

MAP (estimated)93 mmHg

How to Use This Calculator

Enter oxygen consumption (VO₂) in mL/min from Fick measurement or estimate.
Input arterial oxygen content (CaO₂) and venous oxygen content (CvO₂) in mL/dL from blood gas data.
Enter heart rate in beats per minute.
Review the Cardiac Output (L/min) and Stroke Volume (mL) computed via the Fick principle.
Use these values alongside clinical assessment — values outside normal ranges require physician review.
