Cardiac Output vs Cardiac Index
Cardiac Output
Quantity of blood pumped by heart into the systemic circulation in unit time.
Normal value: 5 L/min
Cardiac Index
In different people, the cardiac output is different depending on their body size. So cardiac output is usually normalized to body surface area. The parameter thus we get is the cardiac index.
Cardiac index = Cardiac output / body surface area
= 5 L/min
1.7 m2
= 3 L/min/m2
