"Cardiac index (CI) is a haemodynamic parameter that relates the cardiac output (CO) from left ventricle in one minute to body surface area (BSA), thus relating heart performance to the size of the individual. The unit of measurement is litres per minute per square metre (L/min/m ). See more The index is usually calculated using the following formula: $${\displaystyle {\text{CI}}={\frac {\text{CO}}{\text{BSA}}}={\frac {{\text{SV}}\times {\text{HR}}}{\text{BSA}}}}$$ where CI Cardiac index BSA Body surface area SV Stroke volume … See more The normal range of cardiac index at rest is 2.6–4.2 L/min/m .
