What Is a Cardiac Index?

The heart index is a value obtained by dividing the volume of blood (liters / minute) pumped by the heart by the body surface area (square meters). Furthermore, patients of different body sizes can be directly compared. Calculate cardiac output in terms of unit body surface area (square meters), called the cardiac index

Heart index is pumped by the heart

The body surface area of a medium-sized adult is about 1.6 to 1.7 (square meters), in quiet and fasting conditions

Two factors that determine the heart index:

1.Heart rate: The number of heart beats per minute.

Heart rate is the number of heart beats per minute. It is usually determined by

Cardiac index (l / min / m2) = [Heart rate (beats / min) x Stroke index (ml / m2)] / 1000
