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.
| Derived value | Formula | Normal |
|---|---|---|
| Cardiac index | CO ÷ BSA | 2.5–4.0 L/min/m² |
| Stroke volume | CO × 1000 ÷ HR | 60–100 mL |
| Stroke volume index | SV ÷ BSA | 33–47 mL/m² |
| SVR | (MAP − CVP) ÷ CO × 80 | 800–1200 dynes·s·cm⁻⁵ |
| PVR | (mPAP − PCWP) ÷ CO × 80 | < 250 dynes·s·cm⁻⁵ |

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.
