WebDec 11, 2024 · There are many ways to measure cardiac output invasive and noninvasive. A simple method is to derive cardiac output from the product of heart rate (HR) and the stroke volume (SV): CO [L/min] = HR x SV. The cardiac index describes the cardiac output corrected for the body surface area (BSA). CI [L/min/m 2] = CO/BSA.
