Cardiac output (CO) and cardiac index (CI) are important hemodynamic parameters characterizing cardiac function[1] and reflecting body metabolism.

Cardiac output and cardiac index are used in the evaluation of patients with heart disease and critically ill patients as well as patients under general anesthesia 1.

Cardiac output can be used for the quantification of cardiac shunts and the calculation of pulmonary resistance 1.

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[2] (SV):

CO [L/min] = HR x SV

The cardiac index describes the cardiac output corrected for the body surface area (BSA)[3].

CI [L/min/m2] = CO/BSA

Non-invasive imaging-based methods...
