All-in-One Hemodynamic Calculator

Derive the whole hemodynamic panel from a single screen — cardiac index, stroke volume and index, and systemic and pulmonary vascular resistance, each graded against normal.

Enter what you have — the panel fills in every value it can derive.

A complete hemodynamic panel from one screen

This all-in-one calculator derives every core value at once — cardiac index, stroke volume and index, and systemic and pulmonary vascular resistance — each shown against its normal range. Enter the pulmonary pressures only if you need PVR.

Frequently asked questions

What does the hemodynamic calculator compute?

From cardiac output, BSA, heart rate, and pressures it derives cardiac index, stroke volume, stroke volume index, systemic vascular resistance, and pulmonary vascular resistance, each with its normal range.

What is a normal hemodynamic profile?

Cardiac index 2.5–4.0 L/min/m², stroke volume 60–100 mL, SVR 800–1200 dynes·s·cm⁻⁵, and PVR under 250 dynes·s·cm⁻⁵.

Do I need the pulmonary pressures?

Only for pulmonary vascular resistance (PVR). Everything else is calculated from cardiac output, BSA, heart rate, MAP, and CVP.
