How does the Cardiac Output Calculator work?

Calculate: CO = HR × SV (in mL) Then: Normal CO ≈ 5 L/min; normalize to body surface area: CI = CO/BSA Then: Normal CI ≈ 2.5-3.5 L/min/m².

Can you give an example of how to use the Cardiac Output Calculator?

Example: Input HR 100, SV 50 mL gives a result of CO = 5 L/min (normal) (Normal cardiac output).

Is the Cardiac Output Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.

How accurate is the Cardiac Output Calculator?

Our Cardiac Output Calculator uses verified mathematical formulas and is accurate to multiple decimal places. Results are calculated in real-time using the same methods used by professionals.
